RE: [Chrysler300] Rear wheel bearings 300H

["'David Schwandt' finsruskw@xxxxxxxxxxxxxxx [Chrysler300]" <Chrysler300-noreply@xxxxxxxxxxxxxxx>]

I replaced the bearings on our F years ago due to noise.

Found the lower section of the bearing stained and pitted from water intrusion.

I suspect from condensation over the years of sitting??

No issues since and we have been lots of miles as many of you can attest to having seen the car now for years at meets

Just a FYI , know a lot about the bad outcomes of messing here , as Rich mentions . I think that story is on the site somewhere about the thrust pins in the sure grip and impact on shims . Done by guy I bought car from , he wrecked the axle . Caused me huge grief on the Dan Ryan driving the newly acquired car back to Boston . As in blocking it at 6pm

.. 

The Timken  style taper roller bearings they used are a work of art . They are not like failure prone GM pressed on ball bearings . Ball bearings marginal on side thrust , Timken love it. I have never had one fail spontaneously . It cost a lot at factory to do all the shims  etc to do this originally . An engineering decision to do it really right. Same thing as used on boxcars on RR. They go literally millions of miles. 

So changing them arbitrarily may not be wise. If ok leave it alone , maybe inspect and put back together with new seals . If not leaking leave it alone? Plus the problem with soft junk or faked bearings arises now. Stick to “real” Timken or SKF . 

I would really leave this alone unless it had failed ... mho .why ask for trouble? 

Has anyone had a failure of original ones? Not “replaced”  ones? 

Bearing failures are statistical unless dirt gets in there . A new one may fail due to clumsy work or dirt .. or just not good quality . Or statistics while first running in. 

Fronts more likely to be hurt by potholes etc — and dirt from “repacking “ or incorrect preloads. Personally I love Timken design bearings . Engineer hat on . Call it an input ... .

Just another 2¢ worth,

 

When I had my mechanic put new brakes on our ’55 C-300, I had him replace the rear wheel bearings.  This required re-setting the rear axle shims..  As an ex-machinist and excellent mechanic, he was able to properly set the system up.  He ended up needing different shims to properly set the system and was able to find some expensive shims on the internet and also had a local shop create some new ones from shim stock-using gasket cutters for the holes.  I feel it is an area requiring care and expertise and that the ramifications of improper process may be catastrophic.  Over the years, I’ve lost two differentials and it is not a pleasant experience.

Mike, I would definitely re-check it per your service manual. You can start with same shims, then check for equal end play each axel. If done correctly, very tedious process.

I am keeping track of the shims for the rear axles. What happens when I replace the bearings?  Same shims? 

 

 

Thanks, Mike Moore
