Re: IRS Rear Wheel Bearing Repack/Replace
Posted: Wed Jun 10, 2015 11:51 pm
I removed one side seal, the inner one and replaced the grease with what I am using, Valvoline Valplex EP. The bearing I removed was a FAG one with one side seal??. I bought the bearings from a very reputable local VW parts house. The bearings originally come from Pacific Parts International in the US. But they are Chinese I think, bummer, we'll see how long they last.
The roller bearings are a different storey. One is genuine VW INA type with the floating outer race, the other is a GEOPARTS brand (again chinese). I couldn't get two the same from the supplier. The Geoparts bearing has a floating inner race. Any how, I tried the Geoparts bearing first as if it got busted I didn't mind. But I just could not get this bearing to fit the hub, it was too large and would not take in the bore chamfer!!. So put this aside and tried the genuine VW item, what a difference, this tapped in very nicely. Seals (Elring) in, axle in and the whole assembly went back together nicely. Torqued up the nut with my new 3/4" drive 46mm socket, sliding bar and large breaker bar using the weight calculation method. I'm pretty chuffed about how it all went, except for the bearings, I'm still a bit uneasy with the brand of inner ball one.
Btw the roller bearing measured ~62.15mm OD. The spec for the original is 62.02mm OD.
I have bought a full rear bearing kit for the drivers side. This has a NACHI 6207 C3 ball bearing and a Torrington Germany roller bearing. This roller bearing is also the floating inner type but measures out at ~62.02mm OD. I'll see how this goes.
