Thread: Defender rear diff???

thanks for the help..it is a 110.. and with the help of the pics it is safe to say it is a salisbury diff...

the diff isn't whining at all at least i can't hear it over all the other rattles

with one back wheel off the ground (handbrake on tight) there appears to be some play between the drive flange and the axle (maybe 50mm at outside of tyre)... but the axle also moves a bit without the prop shaft moving...

does this indicate some slack where the axle meets the diff?

when i've got some more time i will investigate further...

FWIW most Sals diffs have a reasonable amount of backlash too, and it's really easy to get some slop between the drive flanges and axle splines, which can make for one hell of a clunk if less than smooth clutch uptake is used.

The slop between the drive flange and axles occurs if you haven't used an RTC3511 hub seal and removed the axle tube oil seals.
Standard, '90's on Defenders sued greased wheel bearings and the axle splines end up fretting from a lack of lubrication.
Reverting to the old style wheel bearing lubrication setup cures the dry drive flange problem.

Using that particular early model double lipped, spring energised seal also prevents water being sucked into a hot hub during water crossings, something that is all too common with the hub seals used in late model Defenders.

As for milky diff oil have you checked the state of the breather and tube ?
A split, grazed or detached breather tubes can easily let moisture into the diff.

Yeah, why is it that they've got so much backlash? It's trained me to be very judicious with the clutch uptake. As for the axles splines, my new (30,000km old) axles are already showing signs of slop with minimal off roading. Looks like a set of the good ones next time round.

An ARB locker will sort that out for you... They seem to have way less slop than the factory sals

hehehe, funny of you to say that. Wait to hear from you on the postage

tomorrow i should be able to get back to you about freight, although had some bad news this evening so may make tomorrow a bit full on. Ill give you a call/ message anyway.

JC

Sorry to hear about the bad news Justin, hope it's not too serious. No problems with the timing from my end, just whenever you're ready; I can wait as long as you want - I'm not a priority at all.
cheers gerald

Very interesting, maybe just cause for me to get a locker.
