V70 G/box: 2WD: Drive shaft Oil seals

[timh30]

Is it a fairly straight forward job to replace the drive shaft oil seals?
i.e.
1.Wheels off
2.undo lower arm ball joint and track rod ball joint
3.swing hub outward
4.pull out drive shaft from gearbox
5.prise out oil seal and insert new one
6.refit in reverse

Volvo changed my clutch a few months back and appear to have damaged the seals as I have a slight leak. They obviously dont want to take any responsibility (nothing new there), but I've negotiated them to 50% (about £120) for the job, but as the seals are not more than £15 for the pair, I may just do it myself if the job isn't that difficult (especially as I may replace the suspension bushes at the same time)?

Bump?



Anyone?

I actually did complete this job, and it was performed as described in my original post. It was a bit of a bugger getting the seal out, in the end I 'gently' persuaded it with a crow bar, being careful not to damage the machined internal surface that the seal sits in. Tapping the new one in with a suitable sized socket was straightforward.

As it turned out, the reason mine was leaking was Volvo had overfilled the gearbox by a considerable amount! (I guess when they changed the clutch a few months previously), as oil poured out even with that side of the gearbox lifted up into the air to change the seal.

P.S I did mine in conjunction with changing the ball joint and wishbone. Be very careful not to over-extend the drive shaft as I believe the bearings can drop out and you will trash the driveshaft if you subsequently put it back unrepaired and drive off ! Also I changed the passenger side only, if you are doing the longer drivers side you need to remove the intermediate bearing holding the drive shaft.

No you have to be even more careful than that...

If they do come to bits... you can't "repair them" correctly and you will be lucky if they last much longer than 1000 miles....

Some crap garage in Birmingham called HLM / VT did this to my original V70, bodged it.. and cost me a small fortune in time and money.

The last one I took apart was on a V70 D5 manual. The inner joint had a what i can best describe as tristar at the inner end of the shaft. Each one had a space ship shaped bearing full of needle rollers.
If it comes apart you just need to ensure all the needle rollers are properly n place and clean, then pop it back on it's star point.. Hold the three in pace, slide them back into the inner joint and refit the boot after filling with the correct amount and type of lubricant. Mine was a type of oil rather than the usual thick CV joint graphite grease.
