You have to remove the rear axles, in order to change the bearings. It's not all that hard. I did it.

www.50resto.com probably has some. I got some with my 5-lug conversion kit.

In order to remove the bearings, you need a slide hammer, which you can rent from a Kragen auto parts store, usually. Or maybe you can buy one.

As far as whether it really is your bearing that's making the noise, I have no idea. I'm not an expert in that subject.

Does the clunking occur only when you are braking?

Does it occur when you are going slowly?

Does it occur when you are going fast?

Based on my shade-tree mechanic experience, "clunking" noises from the rear is usually a gear (ring/pinion) problem; bearings usually make "whining" noises.
It can also have nothing to do with the rear-end; could be within the suspension.

It occurs all the time. I can mostly only here it went i put it in neutral, and also in neutral n braking cuz the exhaust is'nt loud then.

Does the clunking noise get faster in frequency, when you are going faster?

Does it slow down when the car slows down?

In other words, is there a "clunk" every time the rear wheel rotates?

I've never heard a wheel bearing clunk. Usually it is a whine, squeak, sometimes a slight grind and occasionally it will sound like humming tires inside the cabin area. Goodluck.

Yes the clunking noise goes with the speed like when your about to stop completely u hear it go real slow. and i can only hear it wen im going fast in neutral and when there are either cars or something so the sound reflects off of. Yes, and i believe there is a clunk everytime the rear wheel rotates but not completely sure.

Well, I was thinking that, if it only happened when you were braking, then it may be a brake-related problem.

But, if it happens when you're not applying the brakes, then I guess it's not brake-related.

Unfortunately, I'm not an expert on this subject, but I'm sure there are some experts on this forum. If you keep this thread alive long enough, I'll bet some other people will be able to help you.

I just had one of mine replaced recently.
Jack up the rear of the car and see if there is any up and down play with the wheel.When my car was on the hoist you could quickly push up on the bottom of the wheel and hear that "clunk" .They have an "offset bearing" you can get that positions the bearing differently on the axle(just in case of any wear on the axle)

Agreed here. A wore bearing won't clunk, at least I've never heard them clunk. They'll have a constant humming noise which will drive you crazy until you replace it.

OK then if it's not the bearing what could it be?

it's not a loud clunk/clicking noise just an annoying low one.

You first need to weed out the unknowns. Does it just do it in neutral or certain gears? I would have someone stay in the rear, jack the end up and listen. Best bet to find out where it's coming from. It may be from the rear end or just some thing that's loose. You could pull the drums and check everything there, but I just haven't heard of a bearing making a clunk noise before.

Block the front wheels and jack up the rear. Place the axles on jack stands and start the car. Put it in first and slowly let out the clutch till it idles in first and one of the wheels are turning. Go to the back and listen for the sound. Before doing this but, while it's on the jack stands, check the driveshaft bolts and make sure everything is thight.

Sounds like this is the best bed.

Have you tried to put it on the jack stands to see exactly where the sound is coming from?

I had a clunking noise like that and it turned out to be my exhaust pipe hitting, also look at your driveshaft bolts to see if they are loose, that has also happened to me. Good luck!!!!
