Replacing front wheel bearings has become quite common place in today's cars. However, newer style vehicles that have pressed in bearings will require a press to remove and install new bearings. Since I have a 20 ton press, I figure it would be easy enough to press out the old bearings and press in some new ones. I also cleaned the knuckles of grease and rust. I put some tape on them and applied a few coats of paint.

Dirty steering knuckles will need to be cleaned of oil, dirt and rust.

They generally do get pretty nasty, especially if a drive shaft boot splits and spits it's grease all over the place.

Here the knuckle has been cleaned off. I should have used the Electrolysis process to clean these, but the wire brush did a pretty good job.

Cleaned and painted

Pressing out the bearings is not very difficult
. Actually, removing the snap ring is the hardest part of the process. In these pics I'm pressing in a new bearing.

Once the new bearing has been pressed into the knuckle BE SURE to apply pressure to the inside of the bearing when you press the bearing into the hub.

Looking good and ready for service.

Intermediate Shaft; Bearing Replacement

The Intermediate shaft connects to the right-side (passenger side) of the transmission. It is supported by a carrier bearing that attaches to the back side of the engine block. Over time this carrier bearing will wear out and fail. Again, having a press is key to getting this bearing replaced.

Here is the stock seal, and a slinger seal on the other side. Notice the rust on the shaft. Seems these GM cars have a LOT of rust......
Intermediate Shaft is a little rusty

Removing the seal was not an easy task.... It came off in parts....
Removing the old seal

Here I'm removing the seal.

Notice that the grease that is used to assist with sealing the bearing is missing.
lost a little grease

Again, note the press doing the work..

Notice the carrier bearing, and the snap ring that is holding it in place.

NSK Bearing 6206DP8

Having the correct spacers and press parts makes these things much easier.
Pressing the bearing out of the carrier

The stock bearing is a 6206DP8. While I can get the exact bearing off the web, I chose to go down to the local NAPA store and pick up a 6206-2RSJ. Here is some good info on the bearing:

Note the shelf that will stop the bearing from being pressed any further into the carrier.

Pressing in a new bearing....

New bearing pressed in, and a clip holding it in place.

Note how nasty the shaft is, it needs to be cleaned of it's rust.

Again, using the Angle Grinder with a wire spool, I cleaned it up and threw on a few coats of paint.

Nice new paint job. This should give some level of protection against the elements.

Once the bearing is pressed into the carrier bearing, the whole thing needs to be pressed onto the shaft.

Again, make sure that you are putting pressure on the inside of the bearing (notice the socket) when pushing it on the shaft. Otherwise, the pressure is being applied to the bearings themselves.....not good.

Cleaned up and looking ready for use.

New seal put back in place.
