front rear u-joints

[towncarblue]

i have a 2002 nissan pathfinder 4x4 auto trans.
its time to replace my u-joints but im having a hard time figuring out which ones are for my vehicle.
im looking for some dana spicer u-joints heavy duty non greasable types

i went to 4wheelparts .com and they told me 5-1310x for the fronts and 5-1350 for the rears.
i called the company dana spicer and they told me that the rear ones are the 5-1505x.

which ones should i get for the rear of my pathfinder???
has anyone done this before??
i want to replace the u-joints with the best ones i can get

A few years back, I was in the same position as you are now.... I also got some mixed results when asked what type of ujoints I should get from spicer...

Here's the complete story here : http://www.nissanpathfinders.net/forum/ ... /?p=481906

I went with neapco anbd I still run them today with no problem whatsoever.,.

would it be safe for me to disconnect my front driveshaft and still drive the vehicle??

[fleurys]

Absolutely... but if you do of course, do not engage the 4x4 at any time and do not leave your 4x4 selection knob to auto. Leave it a 2wd.

** Super important** before you remove the driveshaft, put some marks (like with a paint pencil, or any other permanent way, on the driveshaft and the connector (where it bolts) On both sides... This way will ensure that once you put it back, you will reassemble both parts the way they were before you removed it.

i bought the same neapco u-joints as the link suggested from rockauto .i have a few questions....

1- i have never greased the driveshaft , doing research i read conflicting grease gun ways to do it.
the first way suggest to keep using the grease gun until grease is seen coming out .
the second way is to just use the grease gun 3-5 pumps.
WHICH METHOD SHOULD I USE ????

2- THE NEAPCO 1-0449 comes with a grease port.
does the u-joints come greased or do i have to add grease ??
if they do come greased , am i better off removing the stock grease and adding in synthetic mobil 1 grease ??
does it matter or grease just grease ??

[fleurys]

1) I do it until I see the grease starting to come out.

2) I think they do come with grease in them, but make sure to try to put some in them to see if it comes out a bit. If not, do it until it does. .I would not change the grease in it.
I feel using synthetic mobil1 grease for your driveshaft and ujoint is overkill. I use wheel bearing grease that come in a grease gun format. The key here is to do it regularly. If you offroad with your truck, do it after 1-2 trails that you had to go in water or sand or mud etc.. If you use your truck on normal roads, have a check every oil change or so...

so .. i went and tried to remove the u-joints, couldnt do it they were in there tight.
i took it to my mechanic and he ended up taking it to a machine shop. the machine shop just replaced them. they didnt bother to check the u-joints.
when my mechanic put the driveshaft in it was vibrating after 35mph.
turns out the rear ones were not the correct ones and one of them was broken. rockauto really screwed me on this one.
i ended up having to buy their cheap a** made in china ones.
and i got charged twice from the machine shop.
now im arguing with my mechanic for taking the driveshaft to a bunch of idiots.
my mechanic is blaming rockauto and im blaming the machine shop.

IF ANYONE EVER PLANS TO BUY U-JOINTS , BUY THEM FROM THE DEALER
OR
BE STUPID LIKE ME AND BUY AFTERMARKET and take the risk
