I have a 97' Expy 4x4 i am getting a rear bumping noise when going over small bumps or even just idleing accross a stone driveway. I replaced all the sway bar bushings with no change. It does have the rear coil springs too. any ideas? The noise is driving me crazy!

 

Maybe the bushings in the shocks?

 

sounds like shocks to me....then again i could be wrong but wouldnt hurt!

 

I had the same problem, turned out to be the shocks...

 

how about some pics of this '97 with rear coil springs...

 

Heres some pics

WOW, such in Good condition! Did u paint her?
why is the under rusty?

 

Yeah i had her painted about a year ago. I bought it from a friend and his now ex girlfriend keyed it from top to bottom even the the hub caps! I have replaced almost everything that was keyed. You can still tell a little on all 4 windows. I only bought it because i got a steal on it and it was almost perfect with no rust on the body. As for the underneath i have no idea why its so rusty...michigan winters mabe..But i have been picking away at it, i got the whole front half underneath done. painted it with chassis saver..its looking good. I just added the brush gaurd and taillight gaurds and im waiting for my roof basket/carrier to get done.

 

i feel your pain.. i bought my expy with no rust anywhere and one winter in upstate NY and rust has started so the battle begins me against rust...I will probably lose if I stay in NY...lol

 

Did you find the cause of the bumping noise?

 

not yet. I looked at the shocks and they look old and rusty! so i just orderd a new set from rock auto. I'll let you know after i get them on.

 

did you paint the door pillars and rear pillars flat black?

 

I havent painted the trim yet. But i do have flat trim paint for it just havent had the time. The back pillars were untouched but the side ones were not so lucky.

 

I finally put the new shocks on today! The old ones were shot you would push them in and it would take about 5min to come back out. Also the shock bolts were badly worn in the centers. Replaced them as well and rides good as new noise is gone.. Thanks for the advice!
