Author Topic:   10 bolt rear leaking from axle tubes
posted May 12, 2003 11:32 AM
I keep having a problem with the rear leaking from the axle tubes. I have replaced the axles with new seals and bearings, but eventually they keep leaking. It is a stock GM 10 bolt with bolt-in stock axles. Is there any trick to keep them from leaking? I'm thinking maybe the axle tubes are just beat up since the car has a lot of racing on it and the drivers side axle did get sheared off last year. I have another rear to swap in and wanted to know if anyone else has had the same problem?

I had one and it always leaked a little out the right side and also was twisting the axle tubes where they go into the pumpkin and was leaking there too.

put a little silicone around the outside of the seal before you put them in

Check the axles to make sure they are true and straight. A bent axle does and will wipe out the bearings and seals. If you have taken a hit square on the rim,or tagged the wall with the tire and rim with the rim taking some of the shock,the rest of that energy goes to the axle. Look into better axles if the ole wallet can stand the loss of some cash.

You need to beef up the bearing retainer plates. Make new ones or buy new ones from Moser. Use 1/4 inch plate. The stock ones deform, the tapered bearing moves off it's race and the seal gets ruined. I had this problem mostly on the left side. Be sure to inspect you bearings if you do find the retainer plates deformed. It usually ruins the bearing when this happens.

Get a new seal and take the spring out of it,
then unscrew the spring,take wire cutters and cut a 1/16 piece off the big end ,then put spring back together,make sure you twist the spring so it holds pressure to keep it tight. put back in seal,use silicone around outer seal,worked for me

I had same problem for a whole year. I fixed mine just like gahainsey is saying except I made two half moon type retainers that could be put on without removing the axles. It worked great.

Great idea, then you only need two heavy duty retainers instead of having to press the bearing off to swap your retainers to new axles. like the half moon!!!!
