OJ you are so funny. Must say currently I ride da beast to work more often due to parking arrangements at home. Beast does not fit into a normal garage bro. Had the merc a year now and only put on 4600km's a bit disgusting hey. However more girls look at da Beast rather than a common old merc, he,hee

I'm going to do my diff this week end, but add Lube later. Then its the actuator thingy!

A word of caution gents - Castrol EP 90 is a GL4 gear oil and is not suitable for most differentials.

Check the specs for your vehicle (sorry I can't at the moment) and I am pretty sure that as with 99% of all diffs you need a GL5 product ie Castrol EPX SAE 90 or with a LS Diff as mentioned Castrol LSX SAE90. Castrol Gear oils with an "X" are "GL5" and just "EP" are GL4 performance level products. Ie Castrol EP 90 = GL4 and Castrol EPX 90 = GL5

The GL5 product has twice as much "EP additive" as a GL4. Use a GL4 iso a specified GL5 and you will have serious problems.

So be very careful - check what is specified for the vehicle and when selecting from the shelf make sure it is the GL4 or GL5 you are looking.

Remeber SAE 90 specifies the viscosity only (just the thickness)
The GL no (1 to 6 increasing in additive level) specifies the amount of additve.

If anyone else is shopping for an axle oil for other vehicles my favourite axle oil is Castrol EPX SAE 85W/140 (seen it at Midas outlets - try a big one I know Centurion has) and is just so good for 4x4 -ers. ie Hilux Pajero etc not requiring a LS oil. Reason being it is a heavier viscosity than SAE 90 and being a heavier viscositynis ideal for those low range obstacles giving a better "cushion" between final drive gear teeth. Is it not too "thick" you ask - Answer is no - we ran trials with a SAE 140 viscosity diff oil in Ford Sierras while developing a product for Gearmax in PE and that was at a constant test speed of 160km/h with absolute normal / excellent wear levels.
The 85W also gives the 140 gear oil a low temp performace so as mentioned EPX SAE 85W/140 is just so good for you serious offroaders. We had a LS GL5 SAE 140 gear oil but I think my successors have done away with it. So sorry for LS diffs you guys will probably have to settle for LSX SAE 90.

[QUOTE=offroad junky;827765]Now you've got me worried..... I had all the oil changed on the 145 000km service (had them do a 120 000km service again because I didn't know if the previous owner had a proper full 120 000km service done which included ALL oils, engine, gearbox, both diffs and T/C) and I don't recall seeing that redline stuff on the Hyundai service invoice....

When I get back in SA I'll have to go see the stealer then because Swambo also complained that she felt a shudder every time she'd reverse out the driveway and turned.... I just made it off as the Cooper tyres rubbing on the rubber splash covers in the wheel arch because mine are loose and I still need to tie them down...

Looking for new tyres now for my 2.9 diesel manual. What size Coopers did you fit? and was it the original rims?

I did the change on the rear diff and now that slip when suddenly accelerating is gone. I'm going to put in a bottle of that stuff to see if it helps as well.

How long does the torsion bars last? When I turn left or right, it feels as if something gets caught and then comes loose causing the Terry to have a slight jolt only once on the turn? Any advice?

Dawie,

I still have the original rims on but got a set of 245/75 tyres if I can recall correctly...
