Step 7 – Put the filler plug back in and tighten to 65Nm
Birth to an old thread but I found it handy!
Changed my oil today and went well. Diff noise has now gone instantly so def worth doing.
Went to bmw and bought the oil and new screw plugs for the diff.
Also the new plugs I bought for the diff are 14mm fixings and replace the original 12mm.
The only query I would have is the diff took about 1.1 litres before spilling out. I thought this isn't quite near capacity but drained for 10minutes. Is this about right what's gone in??
oil leak at lsd
great tip for the oil i am looking to do same i also have o leak at prop seal but have been told this is a specialised job?
was changing seals easy, was told you need special tools?,i have the grinding noise but thought it was due to leak at prop and needed topping up, was going to top up with standard but will now use new oil,may try seals if no special tools required.
For the output seals you don't need any special tools. You can use the old seal to drift the new one in.
Make sure you drift it in square though.
There is a deal from Opie Oils (a forum sponsor) you can get the diff oil and separate FM booter (made by Redline) for £33
The OEM oil from BMW shown earlier in the thread is about £90 for the three bottles required.
Opie were recomending this: Castrol Syntrax Limited Slip 75W 140 (Formerly SAF-XJ 75w-140) :
Is this the Friction Modifier?
I am thinking go OEM here..
Diff oil from BMW is now £99 inc VAT for the three bottles after recent price changes
3 times the price of Opie's deal then!
mmm - £45 from opie vs 99 for BMW
Well I changed my diff oil in january. Noise was totally eliminated but its just started again about 4000 miles after changing it! It only does it when car is cold from what I can tell but disappointed its back so soon, especially with the price I paid for the OEM oil
Did you go for this or the BMW oil? I know everyone always says oem but that originally caused the issues so why trust them again, would this aftermarket set up provide better protection?
I know how you feel. My diff had a slight oil leak from the o/s shaft. So i replaced the seal and put in new oil from BMW for approx £90. after a couple of 1000 miles it sounds a bloody site worse than before. I guess this means the diff is on the way out!
I will try Opie's stuff SAF-XJ and the RedLine FM additive.
just a quicky, where the hell do you put the oil in ???
In the plug above the one you drained the oil from
UPDATE: The noise has now disappeared whilst still on the BMW oil i put in.
Sorry for resurrect such an old post but did you go for the Opie alternative or BMW's?
Apologies for a thread resurrection but if I was to use Castrol Syntrax Limited Slip 75W 140, would I need a fluid pump to refill the diff or is it possible to top up using the above bottle? (does it come with a nozzle?)
Or should I be using something like this? (struggling to find this as well)
Also how much of redline friction modifier should I use? Is it best to fill with this first and then top up the rest with the castrol diff oil?
