02 Exploder 4x4 Help needed

[SVTCOBRA]

I know! Sell it right?

Well, I might, but this is the 4x4 that I repoed from my oldest and would like to know what the shutter is.The shutter or vibration lasts for 1 second (count of one one thousand).'

The shutter occurs from a stop when turning after you start moving.The shutter also occurs from a stop when turning going in reverse.The shutter DOES NOT occur from a stop going straight forward.The shutter DOES NOT occur from a stop going straight in reverse.

Sometimes the shutter happens when going down the road and you apply more gas.... Initially, I thought it was a caliper sticking, but the brake pads on both sides look the same and the shuttering only when turning doesn't add up....

Any thoughts or insight would be great!!

I KNOW there are some other FURD owners out there and maybe a few 4x4 experts..

I have posted on a explorer forum, but only hear crickets...

Check your power steering fluid. Sometimes it can be low and that puts extra strain on the motor while turning the wheel and accelerating

Also check to make sure your intake is clean and has a clean filter!

If your motor is having trouble while first accelerating then it could have a problem with the intake and not getting enough air!

It could be both

Power steering fluid is full and just cleaned the K&N. Thanks Tampa!!!

never owned a FURD Not Used to these types of problems

Good luck!

Sorry this isn't a helpful post but I just have to say that the description reminded me of a math problem or something... "If all these conditions exist and are proven to be true, what is the value of the shutter as the limit of x approaches infinity."

I hate math.

what is the status of your A)motor mounts B)transmission mounts?

Is this a V6 or V8....4.6?

With the wheels blocked have your wife sit in the cab and shift from park-reverse-drive and back. You stand at the front of the truck with the hood up and watch the motor move.

4x4, have you ever changed the diff gear oil?does is have the Ford LS at either end? Could be LS binding up a bit.

[awdjdmtalon]

+1 w/ GWOODS.

Also check the U Joints.

Is this a part time 4WD or full time 4WD? Could be in the transfer case. I know that the full time 4WD had a problem w/ the chains in the X-fer case going bad.

[Tampa G35 Sedan 6MT]

You better hope it isn't a problem with the 4X4... That could be expensive!

[tollboothwilley]

I've had this happen with U-joints in the past...when it binds up it can have this vibration and you can hear it coming from under the car if your windows are down.

DOes it matter which way you are turning? if yes, then i'd check the motor/transmission mounts.

^^^^^^+1To me it sounds like the absorber for the engine(engine mount). Sometimes it doesn't even look like it is bad till you rock it as Jeff suggested it. Only thing strange it does not do it on straight. It might be on the side. Also if it is not a full time 4x4 you should put it in 2x4 to eliminate your problem.

But my money is on the absorber.

This gives me an idea on my truck's problem as well.... The truck goes out of gear (I.E. neutral) whenever I turn left, but only intermittently. After I rev the engire up a little, it kicks into gear and goes on about it's business. Never has happened when I turn right... odd, eh?

Sorry! I have BS in Math..

Exploder is a auto 4x4 with Hi and Lo gears.4.0 V6I do not believe that the transmission or diff have ever been serviced.Purchased the car with 67K on it.I do believe it's LS in the rear,

Thanks for the responses!!!! I posted for help on the Explorer forum and still only hearing crickets.

I'll give Jeff's suggestion a shot.

[Tampa G35 Sedan 6MT]

Good Luck!.... You going to need it when working on a FURD

[CrackaLackin]

On my old 96 intrepid, I was once running on 1.5 out of 4 engine mounts.

That was the second time a mechanic told me I was riding with jesus in that car

[infinitgkid]

Sorry! I have BS in Math..

Well now that you mention it... you should help me with my math homework whenever I get some, which I'm sure will be very very very soon...

[G_whizz]

I have nothing to add as Jeff gave you some great ideas.

I hope you figure it out Rich and it doesn't cost you $$$.

But I would like to give a to all the boys that chimed in to help!

That's what makes NICO #1

Nice job boys!

[Tampa G35 Sedan 6MT]

LOL... I might need to ask one of you boys about the GF's Jeep that has me stumped!

1997 Jeep Wrangler 5 speed manual 4.0 L I6 4x4

When the motor is Cold and you start to drive in each gear at about 1700-2200 rpms there is a hesitation! You can floor it and it doesn't do anything! It takes about 2-3 seconds before it reacts or if you shift.

If you Floor it and hold the gear it doesn't do anything but hesitate. It makes this clunking noise coming from under the hood.

I tracked this noise down to the throttle body and when you WOT it from under the hood or from pushing the gas peddle it makes this noise when the motor is off!

Do you think it could be a Throttle Position sensor or do you think it is the IN tank fuel filter that is clogged.

I changed the plugs and wires and it made a big difference! Not it hardly does it! I also ran a tank with lucas fuel injector cleaner!

What do you guys think it could be?

[cheapazz]

I hate to ask the obviously dumb question here but no one else has yet.....Is the transfer in 2 or 4 high. If in 4 whilst driving on dry pavement it will cause a shudder or "walk" a bit around corners but be normal in a straight line. I would run the transfer through high and lows and N a few times. Do you get a thumping noise from the pass side at all?? The Exploders had a huge "normal" problem with the bushings on the right side suspension where it mounts to the frame....right next to the exhaust. That could also cause an uneven condition in the suspension and cause a shudder. Could it just need a tune up??? The extra power needed to move that thing while the wheels are turned may be just enough to show off a worn or improperly gapped plug or bad wire. Oh yea....check the balancer on the crank.....Ford makes a real crappy one, see if the rubber is coming out from between the two pieces.

[SVTCOBRA]

Thanks again guys for the replies!!!!

I've been leaning toward a LS diff problem because it only does it turning, but that occasional shudder at 35 or 45 MPH going straight doesn't fit.....So, might have a couple of issues other than the obvious one that they circled (see avatar from Joe).Still need to try putting a load on the engine to see if it wants to jump out of the engine bay.

Might just sell it, any takers???

I've already sunk $450 into it since I repoed it. The 4x4 does work again!!

[Rivalry]

Time to buy a G!

Haha, well.... if everything goes right soon, I could hopefully end up with one

^ ouch!!!!

I have rhino ramps, a craftsman floor jack, 3 sets of jack stands and now a new, bigger floor jack that my neighbor got out of a dumpster at a race shop that went out of business!!! Actually, he got TWO and kept the other.It's missing a handle, but I will get one or make one.

Anyway, I stopped by my Ford dealer and they suggested putting in a bottle of Friction Modifier. With my discount, it was around $5.So, I put it in today, and the shudder is not as pronounced already.They said it would take about 100 miles to tell

Thanks again guys for the quick responses!!!!

NICO is by far the best forum!

[gwoods]

cool! If the diff fluid has never been changed DO NOT change it. The friction modifier should do the trick.

I had to rebuild the trac-loc on the Hemi twice and replace the bearings in the diff 3 times in 57k miles.

I actually have a complete rebuild kit for both with fluid and friction modifier sitting in my garage a year later. LOL

I would still look at your motor/transmission mounts. They are a wear item too that can make a noise/shutter like you described.

[SVTCOBRA]

Thanks Jeff!!!Yes, I will check out the engine! Probably tomorrow.

[Tampa G35 Sedan 6MT]

Nice work!

[gwoods]

600 hp + wheelhop = crushed pinion bearing

[Tampa G35 Sedan 6MT]

Yea I wish I had that problem... 600hp

[gwoods]

just takes a power adder your halfway there

The first time I destroyed the pinion bearing the nut that was put on with a 460lb impact gun was finger loose. The Pinion bearing had seperated and the inner race was melted to the shaft of the pinion gear. I had to use a air hammer to get it off LOL I had one rebuild last less the 600 miles

These are 285/60/18 otherwise known as 31x10.5
