Thread: Wheel bearing faiklure on pro street rear

Tweet

With a little over 7K on a complete new rear assembly , I had a wheel bearing crack . Any body think the wide tires could have Caused it's failure ?

Don't know for sure but I realy don't think that would do it.

Probably not the wide tires did it....but maybe not enough backspace on the wheel. I like the wheel center to be as close as possible to the middle of the wheel shell.

Who did the housing? Any chance it was warped a bit when welded???

All the cracked axle bearings I have see were on badly done housing narrowing jobs--no alignment and sh ttie welding methods----

What you are saying is I probably have a badly done narrowing job . Is there any cost effective way to correct the problem ?

what type of rear end is it??? there are various packages for the different rears---like the c-clip axle rears can be changed to axles and bearings like on the ford 9 inch and eliminate the c clips--any way you go, it needs to be done with an alignment fixture and it will entail cutting off the ends of (if crooked) your housing and re doing----I would probably use a pair of new ends also

It's a 9" Ford .

If it's a tube that got warped out of shape from welding, it can be straightened in a press. If an end is on crooked, it will have to be cut off and rewelded. You'll need an alignment jig to check it and see if and where it's bad.

Do the axles slide in and out of the housing easily, or is one or both binding when taken out or installed?

We were on the way to a car show and when I slowed down for a traffic light I heard a loud growling type noise . did it two more times so we pulled over called a rollback and had it taken to buds house where he has a lift . On the lift we noticed oil /grease on the dr side tire ,looked like seal was leaking . After removing the tire and removing the axle bolts we had to struggle a bit to make the axle come out .Don't know if i would call it a bind it just seemed to be tight then all of a sudden it popped right out .Ran out of time Sat eve and did not work on it today .Maybe I should pull the other one to see how it comes out . Thanks for the info guys .

Also, look and see if it's a Timken or other quality bearing and not some POS import junk.....

Thats sounds bad, with proper alignment etc and cracked bearing it should have fell right out. How about a pic of the axle and bearing?

You have a bent housing. I have run into this before.

Cracked bearing was made in USA . Got a new one put on . When installing axle on truck it slipped right in . Bolted it up ,checked fluid level in pumpkin , drove it home - 5 miles - no noises . Parked it for now as I am in process of getting my rat ready to go thru insp . Will mess with 47 after 39 is on the road Also bud with lift is finishing up a rat truck project and his garage is kinda full right now . Probably will have more questions later . Thanks for the help.

If the new one slid in easy, maybe it was just a bad bearing. It happens.

I had a 9" in my pro street Dart.........was narrowed and the wheels were 15x15 with 4" backspacing..........drove it for 9 yrs before I sold it and never had a problem.
