I just got my 2 quarts of redline oil and had a shop put it in. They drained it completely and filled it till it started comming back out the fill plug but it did not take the whole 2 qts ? Was it supposed to take the whole 2 qts ? also I noticed that when I go sometimes I will hear a clunk in the rear end ? It happened twice on the way home , I would step on the gas a little and hear a firm clunk ? I got home, went back out and it didn't happen. Went home again and about 2 hours later went back out, well when I went back out the car felt a little laggy backing up from my driveway and when I went to go the car clunked once again ? Could there be not enough oil ? I watched them fill it till it came back out the fill plug. Does the new oil have to warm up first ? I do notice a difference in driving, It feels alot quicker ! But am I to worry about the clunk ? Thanks

 

it didn't take me 2 qt neither, almost, but not all. and weird, i have no sound whatsoever?

 

Do you have TRD LSD installed? If so, you need diff oil. I have that problem when I got the trd lsd instlled... the shop just use reg diff oil. With TRD, need 85W140. I use the royal purple.. and the problem disappear 99%.
