Upper Links

[qship96]

Getting ready to replace links-noticed Nismo bushings are available for swapping into worn out upper links,and considering ordering them and rebuilding old links for the next time these need changing.

Nismo markets these bushings as stiffer than stock for better control,wonder if they would last longer? Anyone try these yet in their worn upper links?

[elwesso]

how much are the bushings?

[qship96]

Bushings are around 22 each,you need 8 to complete both links,so there is no money saved after you pay to press in vs getting new links from Joe....Unless these Nismo bushings are more durable and make the car handle better.

Any idea how these bushings get pressed in/out? I never knew there was 4 individual bushings in each link-I assumed there was 2.

[elwesso]

They have 4 because they put in one from each side, thered be no way you could press in a single bushing like that with the rubber collars...

For me, I would either go with OEM from Joe or get the solid uppers, no real point IMO in upgrading the UL's without having adjustability.

[Q45tech]

Over the year I've replaced 9 sets of upper links just a part of the typical every 30k suspension rehab just like shocks and tension rods at 60k.

Obviously each 90-96 is a little different depending on local road roughness and handling agressiveness/tires, etc.

Yes,but would the NISMO bushings have reduced this replacement interval due to their more robust construction is the real question......Shocked that this has not been discussed here before,both from a longevity point and a possible increased performance angle.Has anyone tried replacing just the bushings in links,instead of the entire link?

[Q45tech]

The oem rubber is part of isolation design so harder materials will allow more impact and road/tire vibration.

Just part of the cost to maintain as new, sure you can spend less to replace depends on your standards.

Just like solid tension rod or rear frame bushings you can make a TRUCK out of the Q.................just to save money.

If money enters the equation you should not be driving an old Q, you should be driving a new $25k economy something, as it may be cheaper over all.

[maxnix]

For extended life, you may want to search out TexasOil's posts on fitting Zierx fittings to lubricate the bushings. Neither I nor Wes can quite understand how this helps, but TO claims it greatly extends the replacement interval.

Maybe you should re-read my post-I clearly stated going to NISMO bushings would not be a cost savings over replacing the entire link,that is not the point of inquiring......it is whether the Nismo bushings would increase performance and have a longer life,so one DOESNT WASTE TIME every 30K {12-15 months for me} dikking with a link issue......I seriously doubt Nismo would introduce the part if there was no upside to its function.

If you have zero experience with replacable bushings in this application,just say so,and move on.

[Q45tech]

We've had lots of experience with owners paying us to install owner supplied aftermarket bushings on Q. They almost always return complaining and pay us to return to oem. Especially tension rods and rear subframes.

Stillen made urethane this and that back in 1993 and still does.

As I said each to his own tolerance. I takes 10-15 minutes to swap upper links when wheels/brakes are off for rotor retrueing anyway.

The problem with changing components is it always shifts the wear to the next weakest link/component creating new and different situations. Upper links tend to get noisey when dirt and oil/water get inside, that noise alone is reason enough to change them frequently.

1.) The problem with changing components is it always shifts the wear to the next weakest link/component creating new and different situations. 2.) Upper links tend to get noisey when dirt and oil/water get inside, that noise alone is reason enough to change them frequently.

1.) Few extend their thinking to the consequences of how changing one component in a system cahnges the functioning of others.

2.) This is probably why TO lubrication of the bushings extends their life.

[QUOTE=maxnix]1.) Few extend their thinking to the consequences of how changing one component in a system cahnges the functioning of others.

So,Nismo engineers are all idiots,and should have talked to you guys first before spending millions manufacturing and marketing all these model specific bushings...get real

ah,excuse me Brian.....arnt you running NISMO bushings in your tension rods???

Again,if you have no experience using these bushings in THIS APPLICATION{upper links},no need to hear guessing.....

[Q451990]

Nothing like asking a question... getting answers, and then getting pissed off at what you get! Maybe you could be the ginuea pig and see how they work? I don't think anyone said the Nismo engineers were idiots - just that changing one portion of the suspension will have consequences on another portion. If there's one thing I have learned from this forum is that everything in automotive engineering is a compromise between soemthing.

Performance vs. ComfortLongevity vs. ComfortPerformance vs. Noiseetc.

The NISMO engineers are probably looking for performance gains at the expense of harshness.

That's not to say you shouldn't try them... but it just doesn't appear that anyone else here has, so there's not a lot of feedback to get before you do.

Yes I do on one G50, and I determined in this case the main risk was to the front strut rod mount.

Hey, someone has to show the noobies the way!

Seroiusly, try them and quit complaining about member's answers, especially those with a better established legacy on this board than me.

moderate - v. 1. kept or keeping within reasonable or proper limits; not extreme, excessive, or intense.

[qship96]

I asked if anyone here has tried the bushing replacement in upper links,so far,all we have is 1 member saying essentially no with another member riding his coat-tails as usual,since he has no thoughts or anything to add worthwhile of his own.....should have guessed the outcome in advance

Oh well,I will try the Nismo bushings and keep the results to myself.

[AlabamaDan]

Nope. Never tried to replace them, but would be interested in what you learn.

If Q45Tech really replaces his every 30k he probably throws away better upper links that most owners have.

[Q45denver]

I wonder if there was any difference between the rubber compounds used on the 1990 vs. the 1995 models. My 1990 seems to be much tighter (responsive).

[qship96]

probobly due to different condition of individual components as opposed to different compounds

[Q45tech]

Rubber hardness is easily measured with a durometer. Bushing resistance to twist is a little more difficult to measure.

"The brake slide pin bushing and boot seal assembly defined in claim 6 wherein said slide pin bushing portion is formed from an elastomeric material having a Shore "A" hardness in the range of 70 to 90, and said boot seal portion is formed from an elastomeric material having a Shore "A" hardness in the range of 50 to 65.

"we specify Shore A 65 hardness rubber bushings (approximately 30% stiffer than the factory bushings) to allow for some level of street comfort."

http://findarticles.com/p/arti...57837

"The inherent characteristic of all rubber bushings is that they are highly susceptible to wear and deterioration over time - hot/cold cycling, road salt and other extreme road conditions will accelerate this condition. This bushing failure problem can occur in as little as 30,000 miles and almost always by 70-80,000 miles.

Some symptoms of this deteriorated bushing problem are: Excessive tire wear; the inability to properly align the vehicle; audible "clunk" noises from floorboard area, especially when turning or backing up; wandering and/or unstable steering especially at higher speeds; unstable braking; vibration at higher speeds.

An increase in braking stability is also achieved, due to the fact that the control arms will not shift or oscillate forward and backward under the extreme lateral loads experienced during heavy braking. "

[Q451990]

Oh well,I will try the Nismo bushings and keep the results to myself.

So you would rather get no answer or discussion if no one has tried them? I think one of the good things about this forum is that there are very few threads that start with a question and get no replies. It amazes me how many one or two post threads you find on other forums... esentially a bunch of people talking to themselves... compared to here where there's alway a discussion of some sort.

I understand your frustration with a lot of answers that sound more like "don't do it, you're crazy to try it" but I don't think that was really what was being said. Only Dennis relaying his real world experience generally with aftermarket vs. OEM bushings.

Of course, we would all like to hear your opinions on how they work if you try them.

This thread is a great example of how the decorum of Nico is poor.

Qship96, a a FIVE year member asks an intelligent question about a possible upgrade to the suspension. Q45tech's response?

"If money enters the equation you should not be driving an old Q, you should be driving a new $25k economy something, as it may be cheaper over all."

Later on what does Maxnix add to the mix?

"Hey, someone has to show the noobies the way!

Seroiusly, try them and quit complaining about member's answers, especially those with a better established legacy on this board than me."

Why don't the two of you remember that you're taslking to a guy who added a turbo to a Q, as well has added numerous bits of valuable info about electronics and the like.

And for Q451990, the solution is to couch answers in the format "I've never tried that but here is my opinion about why it will/will not work."

just my 2cents.

I am not the guy who did the turbo,that is qsiguy,however I am glad someone else around here can see the decline around these boards...

for q45tech to make that lame comment regarding affordability...all I can say is look in the mirror,and you will see the frugal face of a penny pincher who installed a used transmission,alternator,a/c compressor,differential,among many other parts from junker q`s,and remember you are the one who hangs around an old converted gas station making friends to save on labor,while spewing your comments like a phoenix atop an ivory tower...maybe he is the prime candidate for his own advice of not being able to afford an old Q .As for Brian,and his legacy comment,what a brown nosing panzie he has become-worshipping another man on this forum like the oxygen he needs is dispensed from anothers pen15-

I am done with thread,wish I never started it.

A COMPLETELY inappropriate comment... I cant believe you'd say something like that... I dont care if thats what you think, this BULL CRAP WILL NOT BE TOLERATED IN MY FORUM!!!!!

You are not doing anything but raising everyone's blood pressures... Fortunately I probably have a few years before I go on vytorin...

I dont think Tech meant to be offensive, but naturally you flip it around and make a complete assbag of yourself....

This thread is done, you all suck at life. Learn to play nice in the sand or FIND A NEW DAMN BOX.
