88 chevy blazer with a shaking problem in the front!! i checked out the wheel bearings, brakes and rotors, harmonic balancer, and the clutch fan .. everything checked out except for the clutch fan so i replaced it and the blazer is still shaking bad.. it starts to shake around 20mph and get worst as you speed up!! so i am thinking that it might be the torque converter.. so i am asking for any info that could help me fix the problem with my s10 blazer.. thanks

 

Have you checked the balance and roundness of the tires?

 

yes i did do that ,, they are pretty new tires.. the shaking really doesn't fill like a tirebalance problem... thanks

 

Does it happen at certain RPMs or does it happen only at certain MPH?
May be a good idea to clean your belt(s), a buildup can cause unbeleivable shaking.

 

if the shaking only happens at a certain speed then you're looking at a tire balance problem. Either that or possibly an alignment problem

if it's happening at a certain rpm, then there's any # of things in the engine that could have a problem.

Yeah this sounds like an alignment problem to me. Do you have a steering stabalizer? If you do it might be bad. If not then you can try getting an alignment. If that doesnt help get a steering stabalizer. This is what most us 4xer's call a "death wobble".

 

i finally found the problem,, i rechecked the driveline and found that the u joint was a little loose!!! thanks to all that replied to my post it was very helpful!!!!
