Hi there,
I had the rear springs/shocks changed on my '82 244 a few months ago and since then I noticed when I go over large bumps, the exhaust pipe knocks loudly against something. I went under the car at a garage, bounced it around and it seems like it's hitting the axle (part where the pipe is tucked near the right rear axle). All the brackets seem to be OK and I checked with a garage who told me that if they put the pipe any lower it may scrape the ground. I am guessing this happened because the ride height is now a bit different (my old springs were saggy).

Any ideas on how to adjust/fix? I wonder if anyone else has had this odd issue.
Thanks!
Anthony

 

Check your engine and transmission mounts. Volvo designed them to break away in accidents...consequently they fail often and make the entire drivetrain lower, including the exhaust.

 

check your exhaust hangers first...they are rubber they tend to wear out and sag sometimes or even break...unlikely that a bad motor mount or trans mount will make your exhaust bounce...but I guess could happen

 

Hi Guys,
The exhaust hangers are fairly new and seem to hold well (though i did notice the muffler is a bit sagging to the right side - but that gives the pipe more room to bounce before knocking against the axle, so raising that I think would make it worse). If the engine/tranny mounts would be broken wouldn't they cause the pipe to be lower and give it again more room before hitting the axle? I do notice that my automatic gear shift shakes over bumps as well (I think it always has). It's an odd one this; I'll also have a mechanic buddy of mine have a look. Volvos... great cars but oddly engineered sometimes
