I have owned a 94 std 4.2 diesel cruiser for around 2 years now and do my share of 4wding. One thing I have noticed is that the lsd is not that great. A friend of mine had a GU Patrol and the lsd was excellent. Has anyone got any suggestions on how to get the original diff to work better, apart from the obvious diff locks? (air locker is on the list of things to buy, but I have to win lotto first!) Cheers Jeff

There are aftermarket LSD's available that would be better than the original, but if you go to that effort then you may as well go the whole hog and get a ARB or Detroit locker (depending on whether you prefer auto or manual lockers).

While the cruiser is a great vehicle with many good points, the LSD wasn't one of them. I've got a 7 year old GQ Patrol and still find the LSD still makes a difference over my mates unlocked 60 series. They are all great 4WD's just gotta deal with the problems inherent to your vehicle of choice. Winning lotto would make a fair dent in my shopping list :)

Jeff change the oil in your diff and try Penrites Limslip 85/140 or lighter(Just check what they reccommend for the cruiser see ) You know then youll be getting the best out of your diff dont be tempted to use the heavier straight limslip140 it is too heavy for the cruiser (Patrols can and I reccommend it highly)

Apart from LSD you have one great vehicle. I put Lokka's in my 80 Series and the difference is amazing. I rarely use 4WD except in more severe applications and when couple with front Lokka's it really is a 4WD and a half.
Happy Hunting and yes that Lotto win would see us all give our toys a birthday.

I second that. Don't waste time and money in repairing old limited slip,just wack the LockRight in (about 2 hours job).

Hi, On my first 80, 90 model purchased in 93 the lsd didn't work through wrong oil, under warranty ( wynns ) they ok'ed work. From the guys that did it, stripped, cleaned, skimed the friction plates and put in a slightly heavier spring. Very effective for 120 000 km . So-so preformance there on until about 60 000km later but getting to non-effective, then traded it. Cost unknown, but at the time the friction plates were expensive.

Thanks guys. I'll try changing the oil first and if no luck, will maybe just put in a few more lotto entries!! Apart from lsd, I am very happy with the 80 though. Cheers.
