blown 944

One very easy way to tell if it is a wheel bearing and which one is to take it around a corner (more of a curve) at the speed at which you can hear it most.

If is stops or reduces the noise if you are turning right it is the right if you are turning left it would be the left

I have done this on 2 different cars and each time has been accurate

dropped off the car at the shop yesterday with one hell of a shot left rear wheel bearing.

the CV went bad back in the spring and, i guess in an unrelated event, the wheel bearing went bad, too. almost exactly 6 months later.

I already ordered them and they are on the way. I'll let you all know if I have problems getting them on. I am going to get a seal puller as recommended, and I might just go straight to a shop with an impact wrench to get those axle nuts freed up. Again, I'll give an update on how it goes.

The bearings are too small a diameter for the stub axle, at least as of 2 years ago. I'm talking about the early steel arms. I picked up a German-made SKF bearing off the shelf from NAPA (they stock it because it's for a VW Super Beetle), and it fit fine.

these "clicking" sounds you people speak of, could you say that it sounds like someting "latching" like the rear hatch?

We replaced the rear wheel bearings, and we have fixed the problem. We also repacked the rear outside CV joints while we were in there. It was a long and dirty job, but we (kid and I) had fun doing it.

Couple of tools we needed. Snap ring tool, and a bearing seal puller. Also, do order new bearing seals. We didn't and had to run down to Napa and pick up a couple of them.

BTW... The bearings we ordered from Pelican worked

We also used the advise from Clark's Garage to get the axle bolts broken loose at a wheel shop. It cost me $40, but I think it was worth it to avoid the hernia from trying to break loose nuts with 350 ft lbs of torque on them.

I will have to try this trick tonight. I'm getting the "wheel bearing hum" at various speeds over 30 (low hum at 30mph, slightly higher pitch at 40mph, higher/louder at 50mph, and scary-loud accompanied by vibration at 60mph).

How would you determine whether it's the front or rear wheel bearing?

Throw the parking brake on at about 40.


I kid...I kid.

You'll be able to hear if it's front or rear.
