ive had my moser 12 bolt in for 10 months now and latley ive been hearing a slight grinding around turns every once in a while, ive also been getting some chatter still and i thought it was from the drivshaft being too long but i had that resized and still have the same problem, is it possible that my true trac diff is on its way out?, what are the usual symptoms, i did not add any limited slip additive when i changed the fluid.

and eversince i had my driveshaft shorted i now have a vibration that gets worse the faster i go. anything over 75 and its bad, new u joints and double checked the balance by a very reputable driveshaft shop, they say its not long enough in ther tailshaft and thats where i am getting my vibrations from,

aproxamtley how long should the shaft be inside the tail shaft of the trans?

also i recently put in a spohn crossmember mounted adjustable torque arm and played with the pinion angle and found no diffrence/ improvement

thanks for all the help

 

im in the same boat my drive shaft is about 1 inch to short.i have a bad vibration that starts around 60 and i have a moser 9in,umi tunnel brace adjustable torque arm, stock lt1 ds thats been balanced but still vibrating.i called moser and they said it was because my ds was a inch to short.
