Need help with rear bering replacement (quick question)

I just removed the passenger side hub and removed all of the bearings except for one. This bearing is the one closest to the transmission. I removed the rubber O-ring and all of the other bearings and seals just fine, but i cannot get this one to budge. Which way does it come out? Is there any secret to removing it? I didnt have this problem with the other side because, well, there were no bearings and all of the inside is worn away so i cant tell if there is supposed to be a lip or not on the other side.

Also are the passeger and driver rear hubs/rotors compatible with each other? My passenger side hub is destroyed and i have an extra driver side so i was just going to use that.

Thanks,
Shawn

Oh yeah, SoCal, the temperature sender does work with aftermarket gauges, but none of the other senders do. Just thought i'd let you know.

There is a circlip you need to remove first. Both the circlip and the inner bearing are removable from the tranny side. You'll need a decent quality snap ring pliers for the circlip.

I think the left/right hubs are identical, but somebody else could confirm it..

Well there was no circlip on the driver side. Will i need to buy one? I bought all of the things in the bearing section on pelican parts, but does that include it all?

Remember this thread?
Rear hub replacement

And the parts picture?


The clip is item 4. One each side. The clip keeps the axle assembly from moving in toward the trans and destroying the trailing arm housing.

Bearing kits don't come with the kit because this is usually not a perisable part.

To make things a bit more complicated, the missing clip comes in variaty of thicknesses, that are to be selected for a tight fit. In other words, you first mount the bearing, and then determine the required thickness of the clip. You could use a feeler gauge to do it. You might have to order this clip from a dealer...

Yeah i remembered that thread, but completely forgot about the circlip. Those things are pretty strong if they can handle me mercilessly beating them for a half hour with a hammer. The nut was loose on that axle stub and destroyed the teeth on it and the hub. I bought two replacement axles, an entire drive control arm hub set up, and i have a perfectly good hub fromt he driver side i am going to use on the passenger side that has no teeth.

The bearings in there actually look brand new. There was red grease all inside which wasnt dirty at all, and the rubber seals were pretty new looking. This bearing in the back looks pretty good so do you think i could get away with leaving it in there? when i was hitting it i was using a socket so i know i didnt dent or bend it. I dont want to leave it in there, but i dont like snap rings.

Shawn, You haven't read the Haynes have you. You haven't gone to www.clarks-garage.com and read his procedures have you.

You have to use your resources.

I'll give you some hints: You don't disconnect the parking brake cable. You use two large screw drives to pry back the pads. You take the calipers off with the two large bolts. Use a wire coat hanger to support the calipers -- don't disconnect the hydraulics to the calipers.

Don't use red grease on the bearings. Use the dark gray moly base grease.

Replace all of the seals. You will bend them beyond usefulness when you remove them.

If you have to pound on any part you are doing it wrong.

I bought blue bearing grease, so that's not going to work?

I have read through most of the Haynes and i have found it un helpful. I read up on the bearings, and wiring. The wiring was helpful, but the bearings were sketchy.

I checked out the gauges and senders on clarks garage, but none of this.

I bought all new seals and O-rings so i will be replacing them. I know they get destroyed when you removed them.

Pry back the pads? I know how to take a caliper off i was talking about the parking brake assembly. when my hub exploded (yes exploded) it wore the center of the parking brake plate out of round. In order for me to put a new one on i have to remove the parking brake cable. I have the calipers off, the hubs and rotors off and all of the bearings out. I just need to replace the plate that hold on the drum brakes for the parking brake.

The parking brake backing plate and possibly the trailing arm wear is the results of not having the clip to keep the inner bearing from moving around.

I just went out and looked at the late trailings arms and backing plates. Looks like just the four large bolts, a clip on the cable linkage and the spring retainters for the shoes.

What i did when doing my bearings, was just left the damn circlip in there, removed the bearings from the wheel and transmission side. Re-pack and replace all parts (except circlip), job's done.

Been using the teleporter again to get that inner bearing out.

Don't know of any other way if you don't remove the clip holding it in.

I was thinking the same thing. I went a little crazy with some brake clean (also went temporarily blind) to clean it all out and there are two of them. You have to remove the one closest to the trans, then the bearing, then the other one. It looks like a PITA.

Should only be one large clip. On the trans side. If you have two clips in there then someone put it back together wrong.

It looks like a clip on the wheel side, but i am probably wrong. I was still suffering from brake clean in my eye so i doubt i was able to accurately identify what was and wasnt a snap ring. I'll take a look at it again tomorrow and see. I still can't get the E-brake cable off. I have the entire drum assembly apart, and there is absolutley NO WAY that it comes off there. It must unhook somewhere else.

I thought Hugh had explained the proceedure perfectly but to repeat; You do NOT need to remove the parking brake cable from anything.

The brake disc comes off after releasing the caliper from the t/arm
(don't dsconnect the hydraulic pipe) When you have the hub and disc off there are four hex-head bolts starring you in the face.
Undo them and the parking brake cable assembly will fall off and the outer bearing will be revealed. Carry on as described in the manual you don't want to read.

I HAVE TO REPLACE THE ENTIRE PARKING BRAKE ASSEMBLY, PLATE AND ALL!!! I am not an idiot. I have all of the bearings out. My axle destroyed the bearings and wore out the center of the plate that holds the brake pads. I removed the springs, pads, and adjuster, and there is no way for the cable to be removed. It is attached to a lever arm.

Where there are the 4 19mm bolts holding in the parking brake plate, there is a round hole in the middle of that. It is where the axle stub comes through to connect to the hub. this circle is smaller than the inside of the control arm bearing housing. When the bearings completely went, the axle wore this piece about a 1/2" out of round at the top. It MUST be replaced. I need to remove the parking brake cable and that is all. Even if i am supposedly wrong i still need to remove the cable one way or another of which Haynes does not tell you.

No i dont want to read the manual because it isnt helpful. You must not want to read the posts becuase i stated all of this before.

Once you have the cable linkage off the cable at the brake shoes, it will pull out of the backing plate

Shawn! I think we are loosing the connection...Shhhssssshhshs Crackkkkeeeellll.....

We need to get our parts descriptions back in phase.

If you haven't take off the parking brake shoes (not pads).

Take the backing plate off of the trailing arm. Twist it around where you can get a clear look at the bottom where the parking brake cable comes in. Should be a short pin with a clip. Remove the clip then the pin. This lever arm should pull out far enough that you can see how the cable is attached. Yes you may have to loosen the cables at the parking brake arm under the carpet.

I'm not sure what you mean. Where does the cable unattach from?
