when I try to engage my 4x4, the gears grind as I am driving down the road...when I have tried it, I have never been going more than 25 mph and never accelerating...it will go in, but I'm sure the griding is terrible for it...any thoughts?

thanks

 

So it's only grinding when you first put it in or it's grinding after it's in 4wd too? If only when first going in to 4wd, alot of people on here, including me will tell you to do it when stopped or barely moving.

 

I went to put my truck into 4hi today and it started bucking up and down. I think I will be stoping from now on.

 

when i engage mine, it quick pops in, and goes like a sonofabitch!! but because the front ujoints are completely shot, i think the caps wore off of the factory joints, it quick pops every once in a while. I know i shouldnt use it, but its been needed! Anyone from around Hastings mn area willing to help me come change em out? Ive got a garage with a lift!!

 

yea it only grinds when i try to put it in...once it is in it is fine

 

Stop and put your tranny in N before you shift into 4.
