My 92 Sc400 has 140000 miles on it. This summer i started noticing some graoining when going over speed bumps or the like at slow speeds. After driving it fully loaded from alberta, canada to southern california the problem is worse. There is significant groaning from all four corners when going over any siginificant bump. Car still handles perfectly, and is stable and handles properly over quick bumps at speed. Any recommendations on shops would be appreciated too. Now in Temecula, Ca.


Thanks a lot

 

Describe the groaning in more detail please.

 

it seems pretty obvious that the groaning/creaking occurs every time the car goes over a speed bump or curb . Same sound when going through large dips at speed. I think it is the springs just because the driving and handiling still seems as good as when i got the car. Its from a vertical compression of some sort......just not sure if its spring or shocks...

 

hmm when u go on like.. "rumbles" ur suspension squeeks? im guessing squeeks mean creaking..

but is that right?

 

it sounds just like a creaking door, rumble strips on the road would not be big enough to make the creaking sound. It would have to be something bigger like speed bumps

 

oo thats weird never had that problem... for me it was lil rumbles and it squeaked liked like NO OTHER... speed bumps it was nothing...


but after it rained.. for some ODD reason it stopped squeaking :]

 

that is wierd. with my car it seems to be more prominent in the front. and it also gets worse when its cold. just acting like a creaky old car, trying to figure out what it is.....

 

This has been discussed repeatedly in threads regarding bushings.
