Rear Lube

[Canadian1968CoronetR/T]

I have a Dana 60 sure grip in my 1968 coronet R/T , want to change fluid because of knock from left side, what does every one use when doing the change what fluids and additives

You'll need to add a friction modifier (additive) 3 to 1 (3ounces per quart).
i won't get into the whole "synthetic vs non synthetic" debate,
(some say to NOT use syn others say its fine, I've used both without issue, (Auburn says not to use syn as well), but as long as you use the friction modifier and the same type of oil (don't mix/match) I think you'll be okay.

I was told to go to dealer and pickup the oil and additive (80w-90 lube, plus the chrysler additive for pos)i. Will do that today.

I had the same problem with my 8 3/4 and went to my local Dodge Dealer and picked up some additive, problem solved....

What additive are you guys using?

I use the ferd stuff, and it smells foul!!

Don't know that any fluid will cure a knock. I use Amsoil in the Dana 60. No modifier was required. Good luck.

What additive are you guys using?

A friction modifier additive

I bought all my lube at the Dodge dealer, the additive was $14 a bottle, Now I have to find someone who can suck all the old lube out, one local garage did not have a vacuum, he thought the drain plug would release all of the fluids I don't believe that will work. still looking
