Iirc 28/26 is the right gears for 3.9, count them and let me know, I will tell you if they are for 3.9 std is 31/31
Hey MarkK you mention right tension. I have a couple of standar step off 4x4 boxes and the chain noise is pretty well chain noisy...One's in my rally car and one in a customer road car with sound proofing etc..
Those boxes always noisy?
Anything to do about the noise???
The rally car is going "Back to the Futre" as in back to 2wd but that leaves wif a noosy box or 2 on the shelf...
Ahhhh soon I can just drop in a nice Toyota Supra diff with a nice 4.3 (our rally roads are big, and wide, and blazingly fast so 4.3 is good for us, and Canadians. (even faster up there---BIG trees, BIG semi-trucks to haul out the trees longways so all the curves and junctions are made for 100 foot long trucks) (FAWWWWK is what I say when we have straight 2 miles long)
