So i got a drop pitman arm to corect my steering angle new trac bar got an SYE and a CV shaft in the rear i have had major vibrations driving at highway speeds i just put new gears in thought it was tires blanced so i got them balanced problem still there removed the front drive shaft the problem seemed to disapper but drove on the highway today and it came back seems to be 60mph and above any ideas?

Thanks

 

is it a "new" cv shaft? if its is used then have it balanced. if its "new" then how is your pinion angle? might need shims still even with sye to correct pinion angle....also something in t-case might not have been put back together right when sye installed?....

you did alot of work at once so figuring out what it is can be hard.

might want to check your gear pattern again too before your toast your new gears if thats the prob.

thats all i can think of for now

 

Thanks the vibration seems to be comming from the front end

 

Try getting it aligned

 

my thoughts as well.
