Rear Axle Bearings need Replacement?

I am in the middle of R&R of rear brakes on my 69 C-10. I noticed that when I turn the axle the bearings make a very squeaky noise(s). They sound as if they are not being lubed. I also drained the differential and do not know if it was low prior to draining. I guess I could measure the amount of fluid that came out. It does this on both sides. There is no play in the axle shaft or seal leakage. I am wondering if I should repalce the seals and bearings? Other than the squeaky noises the bearings make there is no other indications that I need to replace. Any advice out there guys?

Re: Rear Axle Bearings need Replacement?

I am going to go ahead and replace the bearings, the noise they make cannot be right and I already have everything pretty much torn apart.

I have priced out Timken bearings which are $10.99 each and BCA National at $18.99 each. Are the BCA National higher quality or just higher in price?

Timken brgs are high quality. Sounds like a better price at that suplier. Those brgs ride on the axle shaft. It would be a good idea to pull them & make sure the axle are good.

The differential capacity is 3 1/2 pints of fluid.

Geoff,

I already jumped into the R&R by the time I read your post. I can still take some pics and post as I have not yet completed the job. I hit a roadblock on getting the bearings/seals out of the axle housing. Auto Zone had a slide hammer available rent free but not the correct puller to attach. All they had was a pilot bearing puller and it is too small. I called around to other parts stores and none have the correct puller. I tried to rig my gear/pulley puller to the slide hammer with no success. I am sure I could rig up something using a threaded rod/washer.... but I went ahead and ordered a KD axle bearing puller kit. I would rather have the right tool and not screw up the housing. Hope it arrives by next weekend

Re: Rear Axle Bearings need Replacement?

FYI...Someone suggested in my thread to use a piece of rebar a little longer than the axle to push the bearings out from the other side....Thanks in advance for any pics and any suggestions...I could use them it sounds like!!!

Here is the thread I started a couple days ago....http://www.67-72chevytrucks.com/vboa...d.php?t=347621

I could see the rebar method working with the differential assembly out but I would be concerned that I would gouge the surface the bearing sits on. Will post pics once get back to the rear, I am finishing the front brakes/bearings now.

Finally got it finished up, have not had much time lately to work on my truck projects with family vacations and kids out of school. My wife finally got tired of the truck sitting on jack stands and taking up the whole garage. I will try to post process and pics in separate thread this evening.
