On sunday I towed my brothers car for 50 metres and ever since my transfer case rattles like crazy is there any common known reasons its a 96 sierra.

Rattles as in rattles inside or the stick moves around?
More info needed.

[Joshua02]

The stick just moves like crazy and it only does it in 2nd gear and up.

Check the t/case mounts for a start.

[Joshua02]

Yeah mounts are tight just double checked them.

[BenT]

Bent transfer case mounting arms would be my guess, or, broken mounting rubbers.

Mounts look fine no damage slight wear in rubber dampene, its doing it in 2h 4H &4L starts at 20 kph.

Its not always really obvious if the long side arm has twisted, but when they do it puts the angles on the drive shafts out and causes vibrations like you describe.

[Joshua02]

how can it twist I wasn't 4wding? Is there replacement arms ?

But you were towing a car which puts a lot more stress on the drive line.

[Joshua02]

Uhh shit alright makes sense so that would twist the arm?

Still sounds like a tcase mount. Put it in low range, 1st gear, put your foot on the brake and slowly let the clutch out until it stalls. If the tcase stick moves a shit load you have a buggered mount

The thing is it only starts rattling when im doing 20 kph and just gets worst and worst. ?

im having a similar problem in my 85 drover. would it be the same. i dont have much knowledge about zooks or cars in general, to start with i thought it was my drive shaft, still havent ruled that out
