Topic: 2 problems with 97 wranglers

[red]

1st problem. 97 wrangler with the 4cyl and manual tranny. when its been driven around long enough to warm up there is this high pitched squeal sound from the engine compartment that dissipates the heavier on the gas you get (only when in gear though). belts fine, tensioner is good, ac on or off doesnt matter. if you let the vehicle warm up in the driveway it makes no noise sitting there. after 2-3 minutes of driving it comes again though. any ideas?

2nd. another 97 jeep wrangler with a 4 inch lift. the drivers side rear shock keeps getting messed up on the upper mount. the little piece of rubber keeps slipping out of the metal ring of the shock tube (this is the 3rd shock in 2 months). is there any way to keep this from happening again? is there a certain shock that is needed?

ok on the first one it could be a multitude of things.  there are no tsb's on that problem.  I think that it might be something with the clutch being that u say it goes away when you are heavier on the gas.  could be that the clutch is not disengaging all the way when the system is getting hot.  this happend in my xj. I guess a way you might be able to test this would be does it go away when you press in the clutch?  the second question ummmmmm got me

that first one seems to sound a little bit like a part called the idle air control valve that is bad on my ford

#1 could it be a vacuum leak?

#2 does the shock bottom out before the bump stops touch?

[red [OP]]

#1 sound gets louder when the clutch is pressed in. noise is very high pitched (like when a belt needs replacement) but higher and not scratchy.

#2 i'll go take the jeep for a drive and try to find a spot to flex out the rear suspension (jeep belongs to my sister's boyfriend).

#2 i was wrong on the lift. its a 3" body lift (just went out and looked at it).

[jimbo74]

pilot bearing? #1

[Willy Mammoth]

Pilot bearing will only make noise when the clutch is pushed in.

Throw out bearing will make noise with the clutch out with light pressure on the pedel and you should be able to feel it in the pedel.

[jimbo74]

so it makes noise regardless of the clutch in or out? possible tranny bearing?


dont see how a bodylift would screw up a shock

[red [OP]]

makes noise clutch in or out, but only when the engine is not under a heavy load (accelerating). if off the gas or idleing in neutral then the noise is very audible (people around covering their ears kinda audible).

#2 i agree jimbo, a body lift has no effect on a shock, was just straightening out my misinformation from earlier. has me baffled though because the upper mount on the shock keeps shifting off of the rubber.
()--------() basic shock on its side (bad i know but i'm tryin to show what i'm talkin about). the rubber that goes in the upper metal loop keeps slipping out of that metal loop (upper shock bushing).

[jimbo74]

on the shocks, if they are eyelets, maybe there is supposed to be a sleeve inside? or the bolt isnt tight enough? not sure how it mounts, but does it use a tube that bolts to something or a single bolt through the eyelet? if its a single bolt, maybe it doesnt have those big bushing washers to retain it --- also seen different sized bushings come with shocks, maybe its the wrong size?


still might be tranny bearing....even in nuetral, fluid can transfer rotations jsut because of its thickness and friction.... i know what im trying to say, but not sure if its coming out right

[DTB]

pics of the shock problem would help....is the shock eyelet slipping off the upper shock bolt? almost sounds like u might be missing a washer or have a wrong bushing

[red [OP]]

#1 its a different type of mount on the upper part of the shock. trying to think of how to describe it, hmmmm.......... heres another shot. the I's are the bolts and the () is the upper shock hoop:    I__()__I. basicly its a bar that goes through the upper shock hoop that is then bolted to the frame on both sides. the bar comes with the shock preinstalled, kinda looks like a T shape on the shock.

wish i'd brought the software to upload the pics from my camera, cant find my sisters camera anywhere right now.

[jimbo74]

red, it does sound like the wrong bushing... i know the kind of shock you are talking about.... doesn't sound like the bushing is right....

the bushing is red, the tube is green, the shock eyelet and body are in black, and the botls are in blue

[red [OP]]

thats it right there jimbo . so can i get a different bushing for the shock or will he need to buy another shock again?

[Ruggedjeep]

Well here is my 2cents. Remove the 3" body lift

Regarding the shock, what brand shocks are they? Yes, you should be able to replace the bushings, id recommend a poly one. But as far as the reason why they're going bad, im willing to bet something is bent. Either the shock or possibly the mount somewhere, so when the shock is compressing its being forced upward in an awkard direction which is resulting in bushings getting damaged/sliding out. This happened with procomp shocks often.

[red [OP]]

agreed on removing the body lift, he's got it their until he can afford to do a suspension lift.

shocks are gabriel ultra's (standard dual tube shocks). just looked over the mounts and everything looks how it should, exact opposite angle to the rear passanger side shock. nothing appears to be bent, though the shock is very close to the gas tank (ride height has about 1/8" of clearance).

[red [OP]]

well installed a new shock back there (warranty replacement) and moved his gas tank as far away as possible. hopefully it wont happen anymore.

with #1 its stopped making the noise, didnt touch anything but its stopped.
