Rear end clunk
Hi all,
My daughter has an ‘05 Impreza outback sport and it just started making some strange noises in the back. There is a intermittent clunking noise along with the sound almost like something is rubbing. I lifted the rear and visually inspected everything (all looks good) and spun both rear wheels. The passenger side makes a kind of rubbing noise but not real bad, drivers side is fine. I was assuming that it might be the wheel bearing and was going to replace but nowhere have I read about the clunking sound with the bearing or hub. Any thoughts? Thanks, Mark

I've had the diff mounts (the two above the rear end of the diff) shred; the diff is then free to roll and makes a loud thunk when getting on and off the gas. Unfortunately they're pressed into the rear crossmember so it isn't a DIY job unless you have a press and are prepared to dismantle the rear suspension. It's usually easy to see - there will be a couple of bolts free-floating inside rubber donuts; you can usually check without even lifting the car - just shine a strong light at the diff from directly behind and look a few inches directly above the diff.

Likely rear diff bushings or swaybar issue.

Likely culprits are:
-Rear diff bushings -Subframe bolts which they make a subframe lock down kit to help with this -Swaybar end links -Rear struts Bearings typically make a buzzing/humming sound on these cars. The above mentioned can make clunking noises under various situations. Chances are one of them is a bigger issue than the others, but given the age of the car, all of them should be addressed and aren't expensive especially if you can do the work yourself. |
