wheel bearings...

Part Number Off The Bearing

Does anyone have a bearing that could check the number on the bearing and the make, not the bmw part number
thanks

seeing that i started this thread almost a year ago I guess I can confirm that what I did actually did work. With as much doubt as there was, it did actually help with the wheel bearing process.

Oh and an answer to your question, look on google for FAG bearings. I know it sounds weird but they make a very good product. I got my bearings from an independent distributor so I couldn't really help you out with getting one. Mine wear about $30 a piece so hopefully you wont have to pay much more.

hope that helps.

Does anyone know of any online deals where I could snag a wheel bearing?
I'm in need of the right rear bearing, though i kinda want to replace both.

Pah. You whippersnappers with your "engineering" and your "correct tools".

the 1st side i did took me like 2 hours.
the second side took me 30min.

Take the arm off. Use a press. Change your t/a bushings while your in there.

Yeeeah. It was hell. Somehow things just didnt...go well. It was horrible. Atleast I did suspension while I was all in there. Let us never speak of this again.

I just spent 6 straight hours working on ONE bearing. ONE! I tried heating it up with butane, I tried a slide hammer...I ended up taking the trailing arm off and beating the hell out of it with a regular hammer for literally 2 of the hours.

dang, and i thought i had it bad (original bearings with 450k). The hardest part for me was getting the axle out. Took a very big hammer and used the socket to hit it out, just messed the threads up a bit.

After that I took the trailing arm off, took 5 taps to get the hub out and about the same to get the bearing out. Didnt think it'd be that easy.

that is amazing I will do my own next time, and forget the mechanic shop

If you've not got a welder or a big slide hammer use a Dremmel with a small grinding bit to grind a grove in the old race thats stuck in the trailing arm, once the race cracks where you've been grinding it becomes so easy to tap out.

This is may be not the quickest or best way to get the old races out but if you are stuck it might help.

If you are going to use threaded bar get some big/thick bar or the threads will strip.

When using threaded bar to pull the hub into the bearing make sure the hub goes into the second inner race properly otherwise you could ruin the bearing.

1. The heat does break the "bond" between outter bearing collar and control arm.

2. The weld bead "pulls" the outer diameter of bearing smaller after it cools down.

Yes the welding does help, but with good tools it's not nessecary.

So my car is whining like crazy from the left rear i assume i have to replace this sucker, what tools do i need so i can do this right?

7. After you weld your bead, find a slide hammer(rent one or barrow one if you dont have one) with the correct sized attatchment and proceed to hammer the bearing out. It took me about 8 or 9 forcefull hits to pop that baby out.

im just wondering what kind o attachment your talking about if i go out and buy a slide hammer will it come with this attachment?

As a pump mechanic / general welder / machinist, (stay in school kids!) - I use a 110v powered bearing heater all the time to slide bearings onto pump shafts that take a hefty puller to remove.

If you have the means, as it's kind of an antique, archaic tool, they make quick work of an install.

You heat the bearing untill 15 sec after you see the first wisp of smoke on the bearing (you lay a little oil in the race to get the smoke) - then with a good set of gloves grab that thing fast and get it on - no screwing around!

You also prep the stub by smoothing any burrs, then a liberal coat of anti-sieze compound so it glides right into place. Hold it with tension for 15 sec or so after placing so it doesn't shift.

2 bearings installed in less than 10 minutes.

Also just in case you have access to one of these beauties, make sure when you power off that you did it on the proper sine wave (electricity) by putting a paperclip on a string & hold it close to the bearing.

If it is magnetic, blip the power switch on & off until de-magnetized, otherwise the magnetized bearings wear out in 1/2 the time or so.

Three and half hours??? Thats fast?? Dude i've done both left and right sides in that amount of time.
