Rear Axle Bearing

Postby chucks302 » Wed Feb 22, 2017 3:01 pm

I'm looking for recommendations for replacement rear 28 spline outer axle bearing & retainer. I seem to get one season out of my L/R the bearing fails or the retainer collar loosens. I follow the shop manual to the letter. What did Ford use for a bearing supplier? Thanks

Chuck, All of my NOS Ford bearings are FMCC or FPP and I am unclear as to who those names relate to. Keep in mind that the retainer does need to be pressed on with a fair amount of pressure to keep it from moving. I at one time thought that I could just hammer it on and all would be good but the axle would slowly walk out of the bearing. Pressing it on fixed the issue.

Thank you for your reply fred, I have always pressed the bearing on first then coller , i guess i will re-measure all the related components for wear, might try heating the coller in oil with a hot plate before pressing it on , im running the car at the drag strip when i have time on the weekends in summer but i dont think thats the issue,

I might try using red or blue locktite on the coller or installing a small set screw through the coller to keep it from moving on the axel shaft

If you are going to try the set screw idea, you will need to grind a slot on the axle for the set screw to bite into. The shaft is far too hard for the set screw to bite into on its own.

Although this might work, I have to wonder what is the problem in the first place that's necessitates this kind of bandaid ?

Ford had a recall on 72 or 73 Torinos for axle replacements and we did a lot of them. I believe that the recall was related to the problem that you are having with the bearing coming off of the axle.

Any knowledge of a similar TSB regarding the 65-70 models ? This issue is certainly news to me as I've never had a bearing or retainer come loose on any 65-70 Ford product once it was properly pressed on. My experience on the '71+'models adds up to a big goose egg.

Now, I have had 28 spline axles snap under enough stress. But that's a horse of a different color.
