sorry for the long post

i finaly figured out wat was making my ct4s slugish raiseing the pulley with washers helpped but still didnt make it perfect so i stripped the rear end apart and found a shit load of diff grease on my bearings and they werent rolling and then i opened my diff case and found that the grease was really thick and tacky is this normal because it wasnt rolling freely

so how do i clean the grease off should i use fuel or degreaser

and should i use diff grease or diff oil and if so wat thickness grease or oil

its for a cen Ct4s


Cheers
