How to change rear differential oil V6S - Non electronic LSD

[stucart]

Gareth.
I've just ordered some of the same oil you used from Opie oils with a view to changing my diff oil at 6 years and 28K miles showing, as a preventative measure not because of a problem.
Just wondered how yours is now you've used it more hopefully during the last few months since you changed it??
One thing that did puzzle me was you put in the stated capacity 860ml but only 700ml came out?? That's not caused any issues?? Leaks??
Thanks Stu.

No issues since, and it’s remained quiet with no leaks apparent. It’s due it’s 6 year service in a couple of months, I’ll be changing it again for what it costs. It will be interesting to see what condition the oil is in.

Gareth,
Thanks for replying so promptly, I'll crack on with mine once the oil and syringe to refill arrive then, let you know how i get on, be interesting to hear what your oil is like as you say when you drop it again.
Cheers Stu

When you drain your oil, drain it through a strainer to catch any bits. It will be interesting to see what you find. Old stocking would do.

Gareth, good tip ,hopefully there wont be any bits!!!

Changed the oil today, as previously said, bit tricky especially with just Rear End on car ramps, only got 1/2” drive extension which is more cumbersome than 3/8” ( did try my 1/4 drive but the 8mm hex bit fell out and is lost in the crossmember/ bracing somewhere! )
Oil was very black, but strained it through bit of old tights and pleased to find NO metallic particles at all.
Refilled with exactly same amount as I drained out , bit of a faff as the Oil syringe I purchased wasn’t brilliant ( EBay £8) but managed it eventually.
Took it for spin and everything appears fine, tried slow speed full lock turns no noises
( weren’t any before either to my knowledge though)
Another bit of maintenance ticked off

Thank you for the information on how too change the diff oil. I did this this afternoon and while I was there I freed up the exhaust valves.
Really good guide My 2015 v6s is on 22k miles, oil recovered from my diff was black, clean with no floater bits.

Did you use the original oil drain plug or replace it with a new one? If so do you have the Part Number?
Do either of the plugs - drain and refill - have compressible washers which need replacing/

[GARETH]

I didn’t. I think they are taper threads.

[gf15]

No compression washers and no collar to compress a washer, so must be a taper thread. I did not replace either of the plugs, but did wrap some PTFE tape around the thread on each one, as there appeared to be some form of sealant on the plugs from the factory. I did torque up the sump plug as per the guidance on this thread. I will check the plug for any drips after a test run.
