Thread: TC braking a diff

yes it does have a chance of breaking the diff although more likely it would take out the axle.

its not as agressive as you might think as its not stopping the wheel dead but slowing it down, as its already being driven the lash is already out of the driveline, admittedly its nowhere near as gentle as a torque biasing diff but so long as you drive it smartly its gentler than a full locker in some circumstances.

I havent yet heard of TC tanking out a diff in an 0 something landrover but Ive heard of a few in some other vehicles I think the solution turned out to be a re-write of the software and a jiggle of the ABS modulator to change the way things worked.

There was talk about this when the ETC first came out, but I tend to think that the ETC is actually better for the diff. Its application isn't particularly violent and it does help prevent situations with excessive wheel spin and then grabbing when the tyre regains traction, the very thing which destroys drivelines and is more likely to be the trigger for the failure which is also when the ETC is doing its job.

mm ok thanks, cos iv been on so meany trips were people have broken diffs an im so afrad of braking one, but i would say 18 of the 20 ive seen have been with people with open diffs, no TC or enything, so i hope it dose helps the diffs in anyway posibul,

but im still wating for the trade mark CRACK!!

It must be me, but why do so many people use low range first when offroad. I was always taught (and of course there are exceptions) that first is only really needed when descending. Second and third I have always found to be adequate when climbing as then you are using the torque and always have another gear if needed.

One of the hills I climbed in the VIC High Country required first gear low, it was that steep. Every vehicle that day went up in first. Looking back on it I could've used second - but I am running Maxi-Drive gears in low range.

If the track is steep enough, you can get in a situation where you don't have enough torque in second gear - eg you come of boost. That usually occurs when you have to travel that slow to maintain control in the first place - as the track isn't a smooth(ish) surface.

So it isn't for 'normal' tracks - Hope that makes sense

well i ues first 80% of the time going up hills.. 1- cos the hills round here are verysteap, 2- realy dont wana brake enything,, 3- i feel i have the best control in first if i slide or somthing cos if i bak off the power,, i can get on it agen realy easly in first

As I said, there are exceptions. But it seems to be the norm to select first when really a higher gear would suffice on most occasions. Using first encourages wide throttle openings which are sometimes detrimental.

My thoughts are usually.....if you cant manage it in second, find another way.
