My wife's 2007 V50 is making a growling noise in the morning when she makes a right turn accelerating from a stop sign. She says it goes away after the day gets warmer.

I drove the car last night but it had been driven on her commute and it wasn't 20 F outside. It didn't make a noise.

This morning I took it out before anyone drove it, the morning was cold. Yep it makes a noise and I have no idea what it could be. I'm accustomed to a CV joint making a clank / clank / clank noise and I don't think I ever had a bad CV joint that healed itself during the daytime.

The growling kind of sounds like a tire rubbing against the wheel well, a very hard rub. I looked and there are no rub marks anyplace.

A strange caliper issue on the right wheel? It brakes straight and true.

Motor mount or trans mount? I need to get my wife behind the wheel while I do the check for a trans mount.

Any ideas?????

Well I didn't get over my lazy mood and the weather veered toward cold. I had an inde shop do the job. Took them about half an hour to replace. The part, labor and tax came to about $225.

Car is now quiet on right hand turns and heading up the freeway ramps. I read on the internet where people spent a lot of money (CV joints, struts, etc) before the mechanic found the real problem, a bad right side front motor mount.

The mechanic asked if I think this is the problem and I said yes...I am fairly certain. Couldn't be 100% sure but in this instance I was correct.

IIRC you have an AWD car with new snow tires. With AWD, the noise could come from a cold bevel gear or even the rear diff. If the noise only happens when turning hard right, I would dismiss the bevel gear and wonder about power steering pump or even a bad hub bearing.

Verify that the new tires are not touching any metal bits of the suspension, but that would be strange as it is seldom that the wheel is turned to hard right even at a stop sign.

Back in the old days, my 1998 AWD had a noisy rear diff that would make strange sounds when cold and turning hard. That was before Haldex.

Keeping it running is better than buying new

Update --

So I decided to have breakfast and then go up to my neighbor, a retired mechanic to get his opinion.

Drove up and by now the temp was about 50F. We jacked up the car, he got his pry bar and went about the suspension check, everything checked out ok. Put the wheel back on and went for a ride. I went to the same places that the car exhibited the noise just an hour before. No noise ... it was quiet. Went through several more 90 degree right turns from a stop and nothing.

There are no marks where anything could be rubbing.

It is as my wife has said, the car is quiet after a while.

Is this an AWD car?

It is an AWD.
