AsianML Date registered: Dec 1899 Location: Vehicle(s): | Squeakey!! I think I hear some suspension creaking/squeaking going over bumps. I remember this was a problem on earlier models? | ||

Is the squeaking coming from the front or the rear? I agree with Marcelc about the bushings for the torsion bar. If the noise is coming from the rear it would likely be the struts...unfortunately more expensive than the front bushings. | ||

My Guess, rear struts.... trusted dealer or a trusted indy.It cost me about 1K at the dealer. I would imagine that you are probably o.k. for a few months (DISCLAIMER HERE), or until it drives you 'round the bend. Edited by phoenix44 3/15/2007 7:37 PM | ||

Ooops..I put my quote in your quote....does that mean we have to get married Any bushing is possible.

Darkmann Date registered: Dec 1899 Location: Vehicle(s): | Re: Squeakey!! AsianML - 4/16/2007 6:57 PM ^^^^LMAO It's warming up a bit, and I haven't heard a squeak since... Let's get one thing clear: is it a "cracking" sound or just squeaking. If it's cracking, most likely torsion bar bushing. Lubing will help but that's just a temp. solution. If it's squeaking (and I think that's what it is since it seems to go away with warmer temps), then here's what I think is happening: The ML's rear control arm uses polyurethane bushings between the inner wishbone (the fat "A" looking piece) and the rear torsion bar. There are a total of four bushings (two sandwitch the torsion bar up top and the other two sandwitch the wishbone at the bettom; in between is a metal sleeve; they are the only white colored bushings in the rear suspension and you can see them by just taking a look towards the inside of the rear tires). I have used Poly-U bushings in my other cars and what MB doesn't tell us (and I'm really amazed at this!!!!) is that over time, if these bushings aren't lubed regularly, they may get brittle and crack, or even disintegrate. I lube mine everytime I get under the truck. Since the noise seems to vary with temps, it's very likely these bushings are the problem. Grab the truck by the roof rack and rock back and forth. You should hear the squeak. Get a can of lithium spray grease and spray both top and bottom bushing sets. Try rocking the truck again. If it's the bushings, the squeak should disappear. Unfortunately, in my experience with poly-u bushings, lubing is still only a temporary solution once they start to give, so even if the noise goes away, there's no guarantee it will not come back over time. But try it anyway. Edited by Darkmann 4/16/2007 10:30 PM | ||
