Loud Clunking Noise

Someone siad that the Ford Product is good stuff..... ????
I use the Ford friction modifier in my Mitsubishi Starion rally car with a tight LSD rear; does the job well. No more lurching around paved parking lots and still grips like heck when it should. Felt like the rear end was going to pop out of the car or a halfshaft was about to explode without it.

That stuff sure does stink; it's like gear oil stink concentrated 10x. So don't get it on you just before a hot date! (And I wrote this before reading Redfish's post; sounds like a common experience!)
