97 PA Hums and Buzzes

Most auto stores will price match on items. I believe Advanced did when I got my UIM.

Are both wheel bearings bad? What's the best advice if only one needs to be done? Go ahead and do the other one? I had a 93 with the old style expensive bearing and did only one at 80K. Lasted till my wife made me trade it at 150K miles.

Also, does that sound about right, that darn much for one hub/bearing assembly? Thanks

Does one need to be done? Or is it best to do both?

Sounds like dealership prices to me. I had a bearing done on 93 leSabre with the older style hub that was expensive compared to the next model year.

Advanced Auto may price match other competitive stores. I believe they did on my UIM by Dorman.

As for torque, I found a store that loaned an inch-pounds torque wrench for my UIM. I used my torque wrench for the caliper slide bolts when replacing my front pads last week.

I use a torque wrench on my wheels--the local chain tire store had at least one out of 5 at 40 foot-pounds instead of 100 last week when I checked. First thing I do when I get home. I lift each wheel and check with my own wrench.

One tire store had set tires to 150 foot pounds on the aluminum wheels on 98 leSabre instead of 100 foot-pounds.

I just think that the left bearing hub assembly needs to be replaced. My car has just over 100,000 miles on it. What causes them to go out? So you all do recommend that I purchase me own assembly and bring it to the mechanic? Damn, I wish I could do this stuff myself.
