When turning tight right the off side rear wheel does a wheel spin. I was not bootin' it either. :lol: Just noticed it for the first time tonight, when turning right at a juction, but for all I know, it might of been doing it for the last two years. :oops:

It does not judder or skip, just spins like it has too much power. Any thoughts?

It's a 4WD manual box.

Cheers.

Yep, open dif. Rear anti roll bar inefective. Nuff said?

Ah, an open diff.

Quote from http://www.yehey.com/lifestyle/motoring ... px?id=7245

An open differential transfers power to the wheel with the least or no traction. On an uneven surface, an open differential does not transfer power to the wheel that needs it most—the wheel with the most traction. When an open differential 4WD encounters a situation that allows one wheel on each axle to hang up in the air, then at this point, this 4WD effectively becomes a 2WD for that period. Confusing, huh? Maybe. However, you’ll know what I mean when you see the situation first-hand the next time you lose traction in an open-diff 4WD.

Nuff said? maybe not quite. :lol:

Silly question time..... Could there be something wrong with my anti-roll bar? I did replace the drop links, brushes, and brackets a short while back.

Hi Brora, now i've given it some thought, i reckon your anti-roll bar is fine, given the circumstances under which you experience wheelspin, it's only to be expected really, your inside (whichever way you turn) rear wheel will always be more likely to break traction,as it has the least weight on it due to turn induced weight transfer, plus, most of the power is fed to the rear wheels, hence "inside" wheel loss of traction on lock&welly. :wink:

I recon your right too BDC. :oops:
It would be the front anti roll bar that could be faulty, well it was late and the wine was good. :lol:

It's a 50/50 front/rear torque split on the Bongo.but the inside wheel could spinup without a limited slip diff as there would be nothing to "tell" the VC to divert more torque to the front.

How do you tell its an open diff from the outside Ste? or are you lifting the rear and turning one wheel to see the reaction from the other?

When turning tight right the off side rear wheel does a wheel spin.
Have you checked the tyre pressure recently? Mine will do that when there's a low or uneven tyre pressure.

Hi Brora,I would think looking inside a Diff,this would be quite normal. Dont worry about it..
The only problem you will get is a baldy tyre.
