diff crusher tube

[bluezeeland]

My '93 Griffith 430 has a leaking GKN diff pinion seal which needs renewing. When doing so, do I need to renew the tube crush washer too ? The method to re-set the preload is known to me. The tube, on drawing seems to be in between the inner and outer bearing, in which case it cannot/need be changed, is this correct ?

Hi Pete,

Cost for the crush spacer isn't much, granted, but the diff is NOT out, and I would rather keep it that way, if at all possible...

I've changed the LH drive-shaft oil seal, in situ, which did leak, and is now sorted.

Today, I had another crawl under the car, and I'm not so sure anymore it is the front, pinion seal which is leaking, having said that; I do not know what is ....

In all, the leak isn't bad (hadn't had to top up after last weekends 1200 kms..) but it is just one of those little niggles which is becoming a crusade...

As I found out the reverse switch in my car is a micro-switch thingy (iso the LR part) and only reachable from underneath, I'm planning to take the exhaust off, renew the switch and inspect the diff & all, and repair were needed,

I've been indeed pointed to John Reid, will give him a call, but the crusher looks, on drawing, to be between the inner/outer bearing, which won't come out in situ anyway, as said I do know the method of re-setting the pre-load...

Thanks for your advise, will report outcome !

After a lot of crawling about.....found the pinion to be dry, so

- both drive-shafts dry

- Pinion dry

- Filler and drain-plug tight (and dry)

- found some oil on the brake-lines, but not apparent to leak (not above, not away from any jointing)

left with;

- breather (can see or reach it without a ramp)

- gasket between body and rear cover
