Hi all
I got GU5 (3.23) gear set, there is "moaning" noise coming from the rear-end -for sure the differential gears- and its louder on highway 60-70 m/h. Also when turning from left to right a knocking sound can be heard clearly. The differential/bearings NOT yet inspected, just I need your answer what are the parts I need to replace all (with same set of gears) I would like to have complete new set with all bearings for the rear-end - yes I know that will cost me $$$$ but - . anyone advice please.
Thanks

 

Check the various "install" kits at the bottom of this page from Thunder Racing:

You need at least the "complete kit".

Have you ever changed the gear lube? Was the GM limited slip additive installed?

 

Thanks!
Yes always with dealer they knew it but not sure did they really add it or not.., anyway planning to replace the lube first with the additive will see if sound will reduce, but still I need to put new parts the sound seems louder than before
