Traction Control broke my front Diff (I think)

Why would it? With a locker engaged, the TC will never activate as both wheels will be turning the same speed.

Staggers - As to "equalling the toughness of the salisbury" - no chance... But an ARB will have a 2-pin cross shaft (and a much stronger housing) - so that kind of wear should never occur.

Another option would be a Tru-Trac LSD. Sam and the guys at haultech have built a few vehicles with TC and LSDs front and rear. They say that that setup is 99% as good as lockers. Many Tru-Trac owners ride the brakes slightly when they lift a wheel. the TC will do that for you - only better!

It will become redundant as both wheels will travel at the same speed;)

good point....;) Think I need to take that holiday now. 6 weeks too far away......:eek2::woot::bangin:

Just tried the 10 taps on the brake before the T/C light goes out technique to disable traction control - and it works! Yeeha.

I agree that 90% of the time T/C is awesome - for mud, when wheels lift etc.. the only time I whinge about it is in soft sand where it seems to do little more than counteract engine power and tell me that my wheels are spinning. No kidding Sherlock... the rooster tails of sand flying off each wheel in a near perfect Cooper STT tread pattern are telling me they're spinning!

Yes, one or more wheels are spinning, TC in this case tries to calculate an average road speed and keeps braking alternate wheels to maintain even spin on all wheels. This alternate braking happens milliseconds apart. I found when the engine labours periodically whilst traversing sand, TC is actually forcing drive to the wheel/s with greatest resistance (grip). This is what keeps you moving on unstable surfaces. TC must have wheel spin to work.

IF ETC is constantly on in sand then your tyre pressures are too high and/or the CDL isn't locked. Drop pressures and lock the CDL. I barely get ETC on in the sand, though if I do it is usually when climbing.

BTW, I do occasionally get the ETC light on while double locked and CDL locked. I just assumed it was from flex in the axles. No pics though. :p

To also add to the conversation, the general thought is that ETC despite the chattering in the driveline is easier on the diffs because it helps reduce big wheel spin that suddenly gets traction - the impact is what causes a lot of damage. In the grand scheme of things, the ETC doesn't produce a lot of force on the driveline.

I gotta ask....

what the hell are you doing to work the TC that much that its spragged the diff (and to me that looks more like failure of the circlip that holds the diff cross pin in place and happens regardless of tc or not). Ive done plenty of soft sand work and barely get the TC to come on...

have you got the CDL? what tyre size and pressures are you running?

Interesting... I am sure I remember Sam (overton) saying many times that TC was hard on axles/diffs in his experience - but maybe that is just in comp situations.

Mal Story once delighted in telling me about a customer of his who had snapped all 4 axles in 1 trip to LCMP in his near new TC equipped defender. I'm sure he must have been driving it hard though!!!

Sam would know a lot better than me. Mind you, he also has an ETC setup which is a lot more positive than an OE setup, but I still wouldn't argue with the man.

I'm with Slunnie. That was my thought....have you got the CDL engaged? If not, why not? Our ETC only seems to engage at max wheel travel and not in soft sand, as when you encounter wheel spin in soft sand, both wheels are usually spinning.

Pretty much the same sort of oscillation would happen in the followng circumstance:

Tyres down to 14psi, CDL locked.
High range 1st or second gear, or low 2nd or 3rd, Wheel speed estimated at 20 to 30km/h, actual rate of progress probably less than half that.
Really soft sand, usually a going uphill, but sometimes on the flat. The car's progress best described as wheels using the 'digging' motion rather than the 'floating' effect because the sand is so soft.

What seems to happen is the T/C picks up a slight difference in wheel speed, applies brakes to the left wheel, so then the right spins, brakes the right, the left spins, so it brakes the right.... and keeps going at a rate of proabably 2 or 3 cycles per second swapping braking/drive left and right (I think). If you drop back to idle the T/C stops but resumes a few seconds after getting the pace up again.

Soft sand is the only situation I get it to happen - everywhere else the system works fine.
