Bongo Fury

I have been looking through the forum to find out which oil I need for the differential as I have a judder which sounds the same as the "Gotta bita judder" post. (http://www.igmaynard.co.uk/bongo/forum/ ... ght=judder)

I have found the lubricants factsheet (http://www.igmaynard.co.uk/bongo/member ... icants.pdf) but at the end it says:

"Differential Oil

On the rear, you should use SAE90(GL5), unless you have a Limited Slip Differtial, in which case use SAE90(GL6)."

My mechanic can get GL5 but not GL6 and he has asked me if I have a limited slip differential.

Please can someone tell me how to tell if I have a limited slip differential?

Many thanks,

Luke

PS - I have a N reg, 4WD bongo.

So does a limited slip differential work the same as locking the differential?

Here goes on an explanation for LSD!

Starting with an ordinary run of the mill Diff, they are fitted to ordinary boring cars to allow the driven wheels to turn at different speeds when going round a corner because the inner wheel has a shorter distance to travel. This is fine while going to the shops etc, but as soon as one or the other of the wheels gets on a slipery patch or gets lifted in the air by driving like me then the lifted wheel starts to spin, the grounded wheel gets no power at all and there is no forward drive, so you slow down.

So sporty cars, or cars destined for slipery terrain get given limited slip diffs which do exactly what it says on the tin...they slip just enough to allow the tyres an easy life on corners, but should slippage occur at either of the wheels it will only slip a small amount and then stop acting as a diferential so that drive to the wheels is not lost in a hooligan or off road moment, and you keep on going.

Some vehicles like racing Karts and Scalestric cars have no diff at all and on corners the tyres have to slip and scrub to sort out the problem, but as the wheels are probably spinning anyway no one cares.

Some of you may get to experiance a no diff situation while using one of those water containers you go camping with that are cylinder shaped with rubber covered rims and a handle that fits balls into each end! If you fill one of those up so it weighs more than anything without an engine should, and you then try to turn it on a hard surface you will feel the forces that your car tyres would see if you had no diff.

Does that cover it? Oh and if you have a LSD and pull away smartish at a wet junction while also cornering you will quickly use up the slip, then the tyres will start to fight with each other, then you will loose some of your traction and both wheels will start spinning and then if all things are going to plan, the arse end of the car (or Bongo) will start to slide gently sideways and you will have to either panic and back off a bit or call up full driving skills. The flip side of this is that you should not be left on a slipery bit of camp site grass slope with one wheel spinning aimlessly while you look out the window to see where all the smoke and smell of burning grass is coming from.

There are a few types of ways of getting these LSDs to work and I'm not well enough up on them to fully explain, but should anyone have one they don't want that will fit my rwd V6 Bongo then get in touch.
