Hi guys..
well i just installed a 2nd hand (30,000kms) Cusco 2way LSD into my 180sx.. i opened the filler plug and checked the insides for oil.. was green and clear. so i plugged her up and installed her. took for a lil drive and its chirping the wheels and very tight.. drove it a bit more and then it made a clunky noise sometimes.. then took on highway at 0-100kph its quiet. then 110 if i accel it makes a slight whine. then settles after 115kph or i back off.. very faint lil whine..
my questions are.
1. what is that clunky noise.. how bad is it.?
2. any idea what that whine could be at 110kph..? and only under accel.
3. what oil do you recommend to service the diff with.. eg. redline shockproof 85w-140?
anything else i should knw about the cusco.?
thanks
mark.
