Exclamation Trac-Lock

Howdy! I just had my rear axle rebuilt. I decided to get a Ford trac-lock from Jeff's BG. My mechanic said that when he looked it up, the ford manual said to use regular gear oil, no friction modifier. He thought it was a little funny. Is this right? I could use an answer ASAP. I have to pick it up in a couple hours.

You need the modifier as it keeps the gear oil from foaming up or that's what I have been told.

Ford's trac-lock requires the friction modifier. If you drive it for long without it, you'll burn the clutches up.

Wherever he looked it up is wrong lol, the friction modifier is required with the trac loc.

Thanks for the help! I'll have to get him to drain it and add ther friction midifier on Sat. I don't have much choice but to drive it till then. Will I be OK? I hate to think of the $$$ I just spent going to heck! I'll probably only put on a couple hundred miles till then. Thanks again everybody!

I have put a little over 30,000 miles on my rear without friction modifier. No problems yet, but I guess I had better put some in.

Well I'll get this taken care of soon. It's real nice driving around w/o all the slop. I kept blaming the slip joint. The spider gears were shot so I went with the trac loc. When the snow hits I'll be glad I did. Again, thanks for all the help. I sometimes post in a panic and forget to thank everybody. This is a great community.
