Tyres screeching

[rustic]

Don't think that when dealers change the oil they put the right stuff in, they don't often sell LSD oil from their spares department. I tried 3 dealers, they said we just put ordinary stuff in..... from that big drum over there....

I had similar problems and used Comma LSD oil 80W90 GL5.
MUST be LSD oil.
As per the other threads, you may need a second change to clear out the wrong oil. When you change the oil, it looks like graphite... silvery grey.. contaminated with the friction material. (this is normal after a few thousand miles).
Also run both rear tyres with the same tread depth and type, same pressures etc and you will notice the difference.
Otherwise the LSD will work over time.
My tyres screech on dry multi-story car parks at very low speed on near full lock. So some screech is normal.
You will need just under 3 litres of LSD oil, a 1/2" wrench, the 1/2" drive fits the plugs as they are. Undo the filler first, half way up the rear diff ( in-case you can't get it out later,) and drain the bottom. You can do this job while it's sat on the drive. No jack required. 20 minute job......Max and that includes 2 cups of tea waiting for the oil to drain. : :
Hope this helps.
best regards, Rustic

I hear a lot about the use of Molyslip, can this be used in a rear diff or is it a definite no,no. ?

Hi some time ago I contacted Richard at Molyslip (link on this site)
He suggested the following product:

"If you plan to do the rear diff, she has an LSD back end so you want to use Multiglide 110ml."

Not used it myself in the rear diff, but I used a combination of Molyslip and Multiglide in the gearbox which reduced the whine in the box by over 80%.
I also use the molyslip engine version, it reduces the stress on the starter motor as it turns over faster and is very easy to start.
Hope this helps. if you want to know info on how much for engine/ gearbox I'll post the info again.
Best regards Rustic

Well, I did the first part of the checks at the weekend.

Although the tyres "looked" OK, I checked the pressures anyway and sure enough they were all over the place. Set them to the right pressures back and front and lo and behold it makes a hell of a difference to the handling.

Can't believe they are so sensitive to varying pressures (they weren't that much out !).

Anyway, going to change the oil in the rear diff this weekend (it was too cold last weekend !).

thanks for all your suggestions.

Tyre pressure is as important as checking your oil or water... if not more so............ tyre pressure can kill you. costs loads in fuel and effects braking

and causes extra wear on stearing and suspension to name just a few


always check your presure at least once a week
