humber349 Posted February 14, 2017 Share Posted February 14, 2017 Hi on our 1928 Buick 114" we have oil leaking along the rear axle main shaft. It overflows though the grease drip and is getting into the hub cap, but not into the brakes. The leak is on the left side only. I cannot see a felt seal or anything similar in the parts list. Has anyone else had this problem please? Phil www.1928buick.com Link to comment Share on other sites More sharing options...
Leif Holmberg Posted February 14, 2017 Share Posted February 14, 2017 The easiest for you is to lower the oil level on the rear axle,no problem to lower 1",the crown wheel will throw out the oil around anyway. Leif in Sweden. 1 Link to comment Share on other sites More sharing options...
Mark Shaw Posted February 14, 2017 Share Posted February 14, 2017 There should be a felt seal and a drain on the outside of the felt seal. But, you may using a lighter gear lube & your drain may be plugged too. I use SAE 250wt that does not leak with the original felt seal material. 1 Link to comment Share on other sites More sharing options...
27donb Posted February 14, 2017 Share Posted February 14, 2017 I must say, I agree with the advice given. One of the best things that all my Buicks of that vintage do, is leak oil. And if it's not getting on the brakes...so much the better! I wish my rear brakes weren't dripping! I switch to Penrite Transoil 250w which I read is equivalent to 600w steam oil originally called for in the transmission and rear axle. So far, my leaks have s l o w e d but I don't expect them to ever be totally gone. Link to comment Share on other sites More sharing options...
Roger Barrett Posted February 15, 2017 Share Posted February 15, 2017 On our cars we have installed modern neoprene seals. There are many ways oil can leak on these. The original felt seal is installed in what Buick calls a shedder that dumps leakage out a tube inboard of the backing plate.The shedder can leak where it is bolted the the inside of the brake drum, or oil can leak down the axle shaft into the hub. We replace the felt seal with a modern seal. Napa number 23300. The shedder must be modified to use it by cutting away the inner part that holds the felt in. We do this in a lathe but it could be done by hand.The shedder is spot welded together and needs to be sealed with silicone sealant between the two pieces. Then the new seal can be pressed in with sealant. Be sure to use sealant when installing the shedder to the wheel. The hub bolts should be tightened and restaked at this time also. This will keep oil off your brakes and spokes. Roger BCA #99 Link to comment Share on other sites More sharing options...
Roger Barrett Posted February 16, 2017 Share Posted February 16, 2017 If oil is getting past the axle and into the hub cap smear the axle taper, key, and slot with silicone sealant before seating the hub. Link to comment Share on other sites More sharing options...
