Title: wheel bearings?
Post by: MoparDan on April 11, 2020, 19:24:53

Started hearing some on and off noise from the left front a few days ago, then yesterday the noise got a lot louder all the sudden and the brake pedal goes to the floor and theres a lot of shaking from the front. I took the left wheel off and I can move the brake rotor with my hand  :o so drove home (what else could I do?) the steering felt weird and inconsistent as did the brakes sometimes going to the floor, other times feeling normal (the brakes are very worn)
I'm assuming the wheel bearings are bad

I forgot I took some pictures. It looks like the cap isn't all the way on

In the next two pictures it looks like the weight on the wheel was grinding against the control arm  :o

Hi Mopar Dan - My guess is that once you take the rotor off, you are going to see some pretty worn parts in there!  Looks to me like complete bearing and race failure - or maybe no cotter pin/tongue washer and the nut backed off.  Either way, most everything in there is probably toast.  It will be fun to see the pieces...  Were those two missing lugs always missing or had you removed them before the picture?  :icon_eek: Fred

Brakes and bearings aren't too bad to replace though it can get expensive in a shop. What will be bad is if the spindle is scored and needs replaced.
You probably won't know until you pull the rotor off.

I have some pictures to upload and a few questions. I will say the spindle doesn't look scored, but I'll believe whatever you guys tell me

Alright heres the first picture of the spindle

One last picture, I wish I'd gotten a picture from the other side...

this is the first picture I took after getting the rotor off, it looks like part of a wing was somehow caught behind the brake, awhile ago there was a wing in the middle of the road and it somehow got caught by the tire...I though I got all of it out I guess not

next you'll see what I'm assuming is the inner bearing, whatever it is its clearly broken!

at first I thought it was part of the spindle, but it came right off (once again this part is clearly broken)

this rubber part is also broken (anybody know what its called and if they still make it?)

as you can see the caliper has a little damage in the corner, is it ok to keep using?

So the spindle looks ok, if it doesn't please let me know. I have another question: I've never replaced brakes in my life, but I found taking the brake apart (and putting it back together) to be very easy, so I'm considering doing them myself. My one concern are the bearings, many years ago she needed brakes and to save me money my brother did them, he's done brakes before (but mainly on Chevy pick-ups) anyways he did something wrong with the bearings, and I ended up having to go to a garage to have them completely redone. So how hard are the bearings to do? and is there some trick to them? I also have afew questions about the calipers: when I started to put things back together I couldn't get it on with both pads on, I had to push part of the caliper back in by putting it the on rotor with one pad and use a screw driver to push it back, I know that can't be the right way to do it, so what is? Next question: I knew enough not to let the caliper hang buy the hose and the only thing I could think of was to let it rest on the frame rail (see picture) is there a better way? Last question: when I was putting the screws back on it would move until the bolts were tight-there was no clear spot where it was supposed to be, how would I know?

Some thoughts to help:
A new rotor will likely already have bearing races installed. races are the hard part.
Spindle does look good.
I would replace the caliper. There is a special tool to push the caliper piston in. or you can use a C clamp and the old brake pad to do it. You should loose then master cylinder cap while doing this.
The trick to servicing the bearings is to really get the grease in to them before installing. There is a seal behind the rear one. Be careful installing it.
Then you tighten the bearing down while spinning the wheel. I was always told you tighten them down until you just start to feel some drag. Then loosen and make it finger tight. Tight enough there is no slop, but not too tight..

What Mark said above is right on.  New rotor will have the races in it already.  New rear seal and bearings are probably available from Rock, but I haven't checked.  Watch a video on YT on how to pack a bearing with grease - any old timer can show you how too.  You want to make sure you have all the washers/retainers and put it together in the right order.  The shop manual will have a diagram.  Tighten as Mark suggested.   I would replace the caliper also.  All in all, not too bad of a job.  Fred

As soon as I get the relief money (or whatever its called) I'm buying the parts and I've got someone who going to replace them, Mary Ellen doesn't want me to do it...
