I have a 2004 Pacific FWD with 80K on the clock. This is really the only problem I have had since the security computer went out with less the 10K on it.

Recently I started hearing a thumping sound in the rear when driving over bumps in a parking lot or an on ramp to the highway. My first thought was the spare tire since it was a little loose, but I tightened it up and it is still there. I know a lot of people have had problems with sound in the front but this is in the rear. Any Ideas?

 

i would check all the bushings in the rear with that mil

 

Also, a bearing might be the problem. Does it make sound when the wheel turns?

 

No it is not in when turning just when going slowish and hitting bumps, like is a parking lot.

I'm digging into it this weekend and report what I find. I was just looking for a starting point if someone else ran into this.

 

Just to let you know, one of the rear shock mounts is out and needs replaced. The Shock seems to be bad as well, so I thought I'd just replace both rear shocks. Has anyone checked the price of the rear shocks for these things. $350.00, WTF. What is so wonderful with these shocks to cost that much. I can get coil over off road shocks for less.
