I put in 8 ounces of friction modifier (Mix with 4 to 8 oz. of Amalie limited slip additive (part # 505-6775). It appears to have corrected the problem to a certain extent. I was only able to drive a short time on Saturday. Out of the 17 - 1st gear left turns, I heard the noise only once. I'm not sure if it was a result of the gear
oil not getting hot yet, or if it is because the modifier worked. Still looking forward to Bob's input once back from Vac.
Bob,
Which diff. are used in the ERA Custom assembly? (See Tom K. reply - 2 or 4 spider gears)
Thanks
Todd
