IT is just not a matter of fitting a new bearing if it is noisy, the carrier bearing that support the differential must be preloaded to a precise tension and the setting up of the crown wheel and pinion to obtain the correct backlash is also extremely critical, this should only be done by a qualified mechanic that is competent with this type of specialist work, otherwise it will just be money wasted.
