V8david Posted July 13, 2015 Share Posted July 13, 2015 Hello all. RRC 1989, front axle... My swivel grease is leaking into the main axle and mixing with the oil, and vice versa. I have the same oil/grease mix in both. Question is, does it actually matter? Nothing's leaking out, everything's getting lubricated, so is any harm being done?

V8david Posted July 14, 2015 Author Share Posted July 14, 2015 Well, with some research it seems it is common, fairly normal and inevitable that there will be some mixing between swivels and diff oil. The seal that does the job is orientated to keep the diff oil from the swivel more than the other way round. Quote Link to comment Share on other sites More sharing options...
110 V8 Posted July 14, 2015 Share Posted July 14, 2015 Long term the thickening agent in the grease (soap) will cause the diff oil to foam up and reduce its ability to lubricate the diff properly. Andy Quote Link to comment Share on other sites More sharing options...
V8david Posted July 14, 2015 Author Share Posted July 14, 2015 Yes, it's not ideal. I'll do regular changes and keep an eye on it. She doesn't go far anyway, not the daily driver. Thanks for the tip. Quote Link to comment Share on other sites More sharing options...
