Afternoon Folks. I'm almost done "dry fitting" all of my parts and start locking things down on my 5 lug disc brake upgrade (88 GT Vert) and I've read through a whole bunch of info regarding filling up the Rear Axle.
Here is what I have:
Here is my question: With the larger diff cover (more capacity) should I put some or all of the 2nd friction modifier in and then fill it with the 2 quarts of 75 - 90 oil? There appears to be such a thing as too much friction mod. Should I just use the 1 bottle of friction mod and get another bottle of RP 75-90 and top it off?
I would really like to not trash the axle because I did not use the right amount and type of lubricant.
Please share your years of experience with me!
Thanks
Here is what I have:
- 8.8 with new 3.73's and a new diff cover (https://www.americanmuscle.com/frpp-finned-88-diff-cover.html) which is a bit roomier than the stock metal can the Axle came with.
- 2 qt bottles of Royal Purple MaxGear 75 - 90, included with the gear kit.
- 1 4 oz. bottle of Ford Performance Friction Modifier as well as 1 4 oz. bottle of Motorcraft Friction Modifier (1 of these must have come as part of a kit).
