Mits Triton rear diff issues-help!

Sounds a bit like the clutches are sticking in the LSD but then it would happen in 2WD as well. Are you sure it's not the front diff thats causing the problem.

The next thing is to change the oil's in bith diffs, replacing it with a good LSD oil and see if that makes ant difference.

Hey Joe,

Are you enaging 4wd and driving on a hard surface?

Read the owners manual about engageing 4WD. It will probably tell you not to do this.

My simple advice to you is DON'T DO IT!!!

I dont know of any part time 4WD that will steer and drive normally on the tarmac. Full time 4WD vehicles are different as they have an unlocked transfer case that allows the front wheels and back wheels to travel more or less independantly of each other while both having drive from the engine. These vehicles have a centre diff lock so that you can manually lock the transfer case up when on slippery surfaces only.

If you use the 4WD system in your car while on hard surfaces like bitumen then you run a real risk of damage to the vehicle. The CV joints may break or at worst the transfer case may break. Both these are expensive to fix. Best case scenario you risk putting large strain on your drive train (uni joints, diffs gearbox, tyres etc) which may cause premature failure.

This is not a LSD problem as rear units perform the same weather in 2WD or 4WD.

If you have a front locker installed (aftermarket product that operates whenever the front diff is turned) then this may be contributing to th esteering problem and noises that you are hearing.

The jumping around and shuddering will be the tyres being pushed against each other because the transfer case is trying to rotate all wheels at the same rate. If you continue driving it in 4WD on hard surfaces the jumping around and shuddering will be replaced by the sound of snapping axles, breaking CV joints or the transfer case breaking into lots of pieces of metal.

Hope that this helps.

Hi joem,

Sounds to me that the good old Triton is just doing what it was built to do. Stop treating it so meanly - you big bully! "Live today as if there may be no tomorrow"

Floyds comments are correct, also it is important to make sure you have the same size tyres and tyre profile all round . If not then you will get what is called transmission wind up, that is the front diff fighting the rear diff through the transmission because of the different sizes. There is always going to be a little difference even with the correct tyres due to wear etc but this is ok on dirt as the tyres can slip to compensate. On the hard surface this can not happen and you will get what you are experienceing, transmission wind up, and the result will be as Floyd has mentioned.
