Something's squeekin'

[Montana Cruiser]

So now its warmed up enough to be Cruisin' around, windows down with your arm hangin out looking cool 8) ..... except now you here a squeeking/light clank coming from the rear when you hit any little bump in the road, so what do you do?

Well, I initially thought it had something to do with the spare tire and that mechanism, wrong. Dropped the tire and drove around, everything sounded just the same. Took it to 2 very trusted mechanics who have worked on my rigs before, one is a Saab guy (worked on my SPG) and another was a mechanic for my FJ60. Both could hear it, but neither could replicate the sound with the truck up on the lift. Both removed the spare and test drove as I did, noise still there. Both inspected all obvious suspension stuff and everything looks and feels tight, all bushings look to be in very nice shape. Anyone experience something similar? Its driving me nuts
Next option might be to go to the stealer.

Here are the facts;
> Cross between squeek and a clank ?
> Coming from the rear end (had someone ride in the back with tailgate open to confirm)
> Only happens over bumps and is a quick sound, not something started in motion and then going back and forth.
> Sound doesnt change AT ALL when spare is removed.
> Sound doesnt change under braking or at different speeds
> Cant replicate with truck on the ground in park and jumping on the rear bumper and pushing it hard side to side
> Cant replicate up on a lift with two people beating up/down/or side ways on the tires with BFHs or shaking the truck in every manor we can think of
> all suspension and spare tire components appear tight and make no noise when messed with.

Any thoughts at all?, this is totally killing the chick appeal as I am cruisin around all shined up lookin good and then "SQUEEK SQUEEK CLANK SQUEEK" a guy cant spend a summer like that, the Cruiser is all I have for a chick magnet .... cant get a puppy either.

MC,
You can't see the rear upper shock mount without removing it. That would be my first guess.

Second (and last guess) is that another forum member posted something very similar a few months ago. His problem turned out to be a bad bushing somewhere in the rear suspension. I'd suggest doing a search but most people whine when I do. Unfortunately, I can't think of a keyword to use and, without a good word, you're doomed.

Maybe the guy with the problem will chime in.

As suggested shock mounts and also sway bar mounts and bushings, upper and lower control arm mounts and bushings, track bar mounts and bushings. Have fun.

What should I check if I've got this sound coming from the front suspension? I have a squeaking sound that happens more over small road undulations than over bumps.

Alaskacrusier,

I've got exactly the same sound over small bumps (or just push on the front or rear bumper in a quiet garage). Could not isolate the noise (something's up with my hearing, I guess); so being pissed, I used Silicon spray on the bushings as Rich layed out in previous post - and this cured it.

Coincidently, I greased my slip yokes at the same time so can't be sure which one help though.

"You can't see the rear upper shock mount without removing it. That would be my first guess."

While this is true, you can tighten the upper shock bushing by feel with a 19mm box end wrench. I would tighten all the upper shock bushings-front and rear-I had the exact problem and this cured it.

Check the torque on the panhard bar bolts. It is not a tight fit from the factory between the bolt and the panhard bushing sleeve. Basicly you are pinching the bushing metal sleeve solid in its bracket. If is not torqued to spec the play between the bolt and sleeve will make the sound you have described. HTH
