Diff failure...?
Turbo Mini Forums

Hi!

I had a very odd steering problem; it needed almost force to turn the steering wheel through a corner. But not always. The problem appeared randomly.

First I thought it's a problem with the brakes (eventhough everythings not older than 3 years - but what does it mean nowadays??).

So today I jacked up the car - and had problems turning the wheel. There's a odd rattling noise from the diff area and every now and then the diff blocked with one wheel on the ground. With both wheels in the air, both wheels turn the same direction...

Rethorical question: is my diff fucked or did someone install a LSD for easter? :)

Cheers,
Jan

Smashed planet wheels, no great suprise.

Diff = Fail

Get it out of there before it makes it's own bid for freedom!

If something is worth doing, it's worth doing half of.

Thought so... :( Thanks guys! :) Engine out time... Might stick the SPVP3 in whilst I'm at it. :)

Cheers,
Jan

WTF is a SPVP3?

EDIT: Google to the rescue! It's a cam

i would opt for a minispares x pin diff,
fit it job done around £155 ish .....

minispares north ask for richard, quick service no bull

Yes, I'm actually considering that now...

What makes me scratch my head a bit is that I rebuild the diff about 4000 miles ago. With a 'competiton' pin & bushed planetary gears. Turned freely and had no play when I assembled it. Must have done something wrong?

Hi Jan,

Sorry to hear of your problem.

Just about all the diff pins available these days are crap. There are one or maybe two that are OK.

You might also find that the fibre thrusts for the diff output shafts have crapped out to.

I'd check the diff housing. If it's worn, the planet gears will not mesh properly on the output shaft gears. Picture?

It's worn now. However, it was like new when I installed it! I took extra care to select a good sphere/diff cage...

Fit a 4 pin diff.

I put a Tran-X one in mine all those years ago...and a damn fine piece it was. The original Withy one broke.

Dont remember either being as cheap as the Minisport one though !!!! Bargain !

Ah I can't decide... @Johnny: PM sent! :)

Teeth still missing. Found only one. I'm stripping the gearbox now and hope I find all the bits...

my mate had that happen to the box casing, it was leaking oil like hell and finaly spat the final drive off pulling out of concentric pumps car park, it was a 4 pin diff as well, turned out one of the roll pins had failed and let a half pin slowly find freedom.
