mrw Posted September 8, 2010 Share Posted September 8, 2010 I have a Power Brute LSD in my 73 240z (v8 6 SP). The rear chatters way too much for my liking. I swapped the diff fluid to Royal Purple Synthetic that has the friction modifier already in it. The chatter was reduced substantially after the fliud change. Can I add more friction modifier to reduce the chatter further? I have not been able to find much info on rebuilding the rear that will reduce the tightness of the rear. I do not want to give up the lsd but I do not race the car and I need to find a way to make it more streetable. The diff only has about 2000 miles on it. I only put about 1000-1500 miles on the car per year and I am guessing that it will take alot of miles before it wears enough to be more streetable. Any suggestions?

cockerstar Posted September 8, 2010 Share Posted September 8, 2010 Go ahead and add a bottle of LSD friction modifier. It isn't uncommon to have to add more than one bottle, so it isn't unreasonable to add just one to a specialty diff fluid Quote Link to comment Share on other sites More sharing options...
JMortensen Posted September 8, 2010 Share Posted September 8, 2010 Just keep adding friction modifier until the noise goes away. You can do figure 8's too to get the FM distributed throughout the diff. Quote Link to comment Share on other sites More sharing options...
Cobra_Tim Posted September 9, 2010 Share Posted September 9, 2010 Convert back to an open diff and give me the LSD? We use Redline 75-90 with GL-5 in our IT car.... Weres great. http://www.redlineoil.com/product.aspx?pid=133&pcid=4 Quote Link to comment Share on other sites More sharing options...
