Question about P2 Engine/Transaxle Mount Failure

[abscate]

Also the bolts are torque to yield one time use only. So new bolts must be installed. June

Don't forget to thank June for this one. Then search for the thread of the guys who scoffed at this advice, then found his subframe bolts finger tight a week later.

Around your year model Volvo had a campaign to replace the subframe bushings only if the customer complained of knocking sound. I tried to find the exact years affected and found a great write up on the 07, 08, and 09 S80, XC70. I realize not your year, but sounds and check procedures described will be the same. I added the screenshots of article below. It gives a good description of potential sounds bad bushings can make and has some good pictures of the bushings themselves. June

So.. the test is.. put a socket on the center nut of your strut and move it left to right... Don't unbolt it. Check to see if the rubber moves. June could be right the subframe bushings. Here's a generic picture of what June is talking about... MDK

P2 does not have subframe bushings moving in subframe. It is real PIA to take old bushings out in fact. There was a question here on MVS or on one of neighbor Volvo forums: how I would press new bushings in? They are that tight!

Sagged front/rear engine mounts drop the engine by a good inch. This puts stress on the top engine mount and crossbar. Crossbar has a weak rubber bushings that isolate engine vibration from the chassis. If they fail you'll be getting metal clunk sound. Have them checked.

I would replace all engine mounts just for piece of mind. When I did mine, plus new subframe bushings, I haven't had any idle vibration on the steering wheel for quite a while.

Everybody-

Thanks for the tips! I wanted to come back and tell y'all the solution. I finally got a chance to do some diagnostics yesterday and I could hear the sound apparently from the hub area. Turns out the front hub bolt was the issue. It didn't seem particularly loose, but tightening it stopped the noise!!

Namaste!

Mark the axle bolt and keep an eye on it. Those are also single use bolts so they May loosen again on you

Be careful confirming the torque setting. My Alldata lists the very tight torque for the nut for my 1999, which isn’t right for the bolt, which is 50 Nm, i believe
