150k miles, time for differential and transfer case fluids

[Jimmy Brooks]

Just hit 150k and both diffs and transfer case needs new fluid. Any specific fluid I should use or just the regular Land Rover fluid. Also could someone link me a pump tool to pump the diff fluid into the diff?


On a side note, anyone know what size socket will crank bolt, need to do an intake decarb but I don’t want to pull the skid plate till I do the whole job.

I use these Royal Purples for the front diff and xfer case, and the AC Delco fluid for the HD rear diff

Here we go on the fluid spec religion train .
For consideration, the oem fluids (as spec’d by the engineering staff) lasted this long…

But I am glad you’re getting it done. By this number of miles, mine have been changed twice.

I used Royal purple for diffs (non hd) and the synchromax in the transfer with no ill effects. I would have supported our local deal but $80CDN for 1L of transfer case fluid is beyond stupid.

Remember manufacturers tender oil/fluids out to suppliers and go with the CHEAPEST that meets their spec. That way they can pad the margin even more. Do you really think a dealer is paying anywhere near $80? Likely $10.

The markup is from the manufacturer. I was in a rush and bought a quart of transmission fluid from the dealer. Parts counter told me they get charged $80 for it.

Had a CJR dealership been nearby I'd have gone there. A ZF 8 speed is a ZF 8 speed, they're all going to use the same fluid.

I used Redline when I changed my diff fluids.

Don’t waste your time or money on the hand held fluid transfer pumps, too cumbersome IMO. Use something like this instead…

The Workshop Manual lays out the specific fluid specifications for all components. Not all substitutions are equal, nor match the spec.
