Hello,

A few question to show my ignorance :) When I do semi-hard U-turns in my XR6 the back tyres squeek (you know, slower version of doing a set), is this normal for a LSD.

And second, whenever I take off fast and I go to second gear (5spd manual of course).. no matter if I trying and slip the clutch a bit or do a snap shift, it always does a chirpy.

Is that normal? I just don't want to stuff my diff thats all :)

Thanks!!!

yep, thats normal
the idea of the LSD is to give positive traction to both wheels, so when you are turning "fast" the diff thinks that one wheel is spinning(due to the turning circles of each wheel being a different size), and it locks up, giving you the slight wheel spin on the inside wheel
you only need to worry if the inside wheel locks up on slow cornering

I showed a mechanic (apprentice) and he got me to hold one wheel while he turned the other and declared the diff is locked (?) and said the oil needs changing to.

I'll be annoyed if thats the case, I'm not sure what it all means when the diffs locked.. does that mean its stuffed? :(

YOOT

Dunno about having an LSD lock on you, more likely it would stop locking and slip more.

Mine shudders when you give it light throttle round a u turn, intead of spinning it goes ch ch ch ch ch and gets faster as the speed rises, alternately it just spins along with the other wheel and you know what happens then

it should be hard to turn the rear wheels independent of one another, ie hold one and try to turn the other with your hands, thats the whole point of them.

if its not possible at all (it should be pretty damn hard but) then its possible that bad things have happened in your diff.

if you can do a very slow full lock U turn and the tyres do not skip then its all good.

Well, I did two slow U-turn tests. One the wheel chirped and the other it didn't.

I should just take it to a proper diff place and ask them to have a quick look.

On a side note (I may start a new thread asking this) but what diff oil should I use in the EL XR LSD diffs?

I checked the manual and I can't find the ones it mentions anywhere.

YOOT

According to my manual it says:

Limited Slip:
SAE LS 90 EP Lubricant, 1.65 litres

My manual says similiar (i don't have it here) BUT then underneath it has something different for XR series. They must have different LSD's?! Anyway, thats the one I can't find.

clevo

I use the 85/140 its more suited to an LSD. If the diff grabs replace it with this oil and it should be fine.
