Thread: Detroit rear locker

There's these as well. A mate has an Eatons in his Mahindra rear end & I have seen it working a few times when following him & it appears to work well.

That is a limited slip diff not a locker.

Its better than a locker

That Ashcroft ATB is basically the same as a TruTrac. Its not a limited Slip.. Its a 'Torque biasing' diff.. It uses a series of screw type gears (3 on the left axle shaft and 3 on the right). It works using friction between the screw gears and the casing, and the gearing between side to side.. A normal open diff allows power to go straight out through the easiest route. These require a lot of power to spin a free wheel, so always put a percentage of power to the wheel that's still on the ground... so working like a limited slip but with a more positive drive to the loaded wheel.. I found the best setup to be a Detroit in the rear axle and a TruTrac in the front axle. There used to be a guy on here from the states who could supply them... He trades as 'Lucky8OffRoad'. From memory they were just over $550 each and he'd ship separately to avoid the customs cost... Mine arrived from the US within a week, and once fitted they made the 130 surprisingly good off road. Cheers.

chaps, I fitted an ATB in the rear of my Puma in October 2017, and recently started noticing a groaning noise that's becoming quite bad.


My indie and I eventually traced it to the rear diff: at specific rpm/speed, there is a loud, low-frequency groaning noise + vibration emanating from the rear of the car. It almost feels as if the seats have built-in massage function, especially when I hit 80-100kmh.


Has anyone else experienced this after fitting an Ashcroft, and if so, how did you fix this?


thanks

For me it's the other way around.
I'm getting ATBs fitted to my two spare diffs, which I'll fit once done and time allows, but doing this due to my rear pinion bearing making loud low frequency groaning noises.
Sounds like worn mud tyres, except that my tyres are more road biased.
This n new noise doesn't change with road surface like the tyres do, so I've discounted tyre noise due to that.
And the noise is predominantly heard at about 80k/h which seems to be a sweet spot for how my D1 runs(smooth and quietish .. well, ss smooth and quiet as a D1 tdi can be!)

Only thing I don't get is any vibration(at all).

When you got the ATB fitted, did you get them to renew all bearings?

I got mine from the US , and I suspect most local suppliers would do the same . Price both , here & there , and get one , they are great .
