First the 'players':
Nothing has been replaced in the rear suspension (shocks, etc)
ProBeam installed, and Magnaflow exhaust, NA version
First suspect was the exhaust/ProBeam coming into contact, as there is very little space between the two, and the exhaust is mounted to the stock mounts, giving it some movement.
(Note that there was no clanging from any PB-Exhaust conflict all the way home from Denver, the clanging began in earnest on the way home from Pittsburgh last month, and has gotten worse since the diff replacement)
Last night I put it up on ramps, I'd already wrapped the exhaust pipe where it could come into contact with the ProBeam, and my vigorous shaking of the pipe could not produce the sound. So I took bailing wire and lashed the pipe to the Probeam tight, removing any movement.
Took it back out, and the sound did not change.
When the driver rear tire hits a bump, the clanging and banging coming from the rear end is deafening. Did some googling last night to come up with a possible list of suspects:
E-brake issue (will test that today by putting it on as that wheel encounters a bump to see if there is any change) Suspect that due to the fact that within the last 2 months the range of travel for the e-brake handle has reduced significantly.
Shock, not leaking, but with 81k miles, it's a possible suspect. Also noted that after the car has been up on jacks for a while, then let down, about 10 feet or so after rolling away, there is an audible clunk.
Brake issues
I've yanked, pushed, pulled and harrassed every metal part on the rear of the Sol, as well as the front, and not coming up with anything to duplicate the clanging. When the pass rear caliper was loose, I was able to duplicate the sound, which was very similar.
I'm about ready to pull my hair out, it's horrid driving down the street hearing what sounds like a junk wagon rolling down the street!
I'd like some other possible ideas, tie rods? U-joints? However the symptoms that typically go with a failure with either of those is not present.
Kenny is going back to the dealer, as the pinion seal is AGAIN leaking in his new differential, so suffice it to say, I am not a happy owner right now. Three tries to fix the leaking original diff, and I have to pay for a new one. Now leaking.
I'd like them to also address the junk wagon symphony, but not by trial and error, on my dime!!
