drops of oil from irs cv joint on gearbox

Post by chrystal » Sun May 10, 2015 4:52 pm

Im getting small drops of oil sittiing on the hottom of the cv joint that attaches to the gearbox. Are there seals that can be replaced and what is involved

Cheers

If it's gearbox oil then I'm guessing your drive shafts are too long resulting in them hammering the rubber seal in the end of the drive flanges when you hit undulations in the road.
I take it your bus lowered as this is a common problem with irs conversions, you'll need to measure then shorten your shafts, re machine the circlip groove and replace the seal in the drive flanges.

As Tufty said. Very common on CE IRS conversions as they don't tell you the axles are too long for most instalations. Less common on T1 based IRS, though it can happen too.

Or maybe the inner &/or outer seals have simply started to age. Both are easy enough to replace, just a bit fiddly and messy.

The cv's are new. For the axles, is there an ideal set to get? I'm using a 1302 box I think with early bay drums

The ones you've got, just machined to the correct fit.

If it's just the seals then they are easy to replace, remove the drive shaft completely, pop out the plastic cap in the centre of the drive flange, prise out the oil seal, then pop it all back together with new seals,

I bought a full irs beetle rear end recently and when I removed the drive shafts the boots were bulging with gear box oil, oddly it was in the wheel hub end too! Not sure how it traveled through a solid drive shaft :)
