My locker was bought new and installed in '92 and all of the complaints that everyone has ever made about them were ever present. Especially reared their ugly heads on wet pavement and snow as the Camaro was my high school ride so it also served as my driver every day. Car went from a decent balance of straight line grip and handling to a car that would transfer power to both wheels at the worst possible moment. Worst decision I ever made on that car was installing a locker on a car that saw more street time than drag strip time. The guy I sold it to made his first project removing the locker and going with a limited slip. After owning it for 25 yrs said that is the only thing he’s done to it and that he’s never regretted it.
True-trac is a great differential! Just not “hardcore” badass! Like i said in the beginning! And… (here we go… Lol!) Lots of women don’t like lockers!!!
I use the Yukon copy of the Locker in my everyday car. I can back Royce up with my experience. It usually only shows its character turning into the pits at slow speed after a hard launch and pass down the track. I suppose it has popped once or twice at the supermarket.
The TrueTrac is very nice, including in northeast winter show. Not as durable for a street/strip car, though.
Wouldn’t do that bud! That there is what i like to call pokin’ fa fa fun! Wait… Maybe… No! Just pokin fun! although one could argue the same with hydraulic cam vs. flat, supercharger vs turbo… Manual vs. auto, Etc! There’s always a more “hardcore” in my opinion!
I have a '69 CJ Mach with an honestly unknown, but non-open rear end (assumed the 3.50 TL per Marti report, but who knows after all these years?). I have owned this car for about 20 years and never had cause to have any work done to the differential (although now that I’m thinking about it, it’s time for me to change that ancient gear oil this summer!). It has ALWAYS made one “clunk” and kind of “shimmied” – just a side-to-side/notch-like motion – when you start driving forward. This is a really small thing, it’s not loud and it’s mostly noticeable in the seat of your pants thru the seat, but it’s been the same for 20 years. No clicking or weirdness in tight corners and the “Traction Lok-ness” seems to work. Is this a TL thing, a TL-going-bad-slowly thing, or maybe it’s not a TL at all?
Sounds like a little driveline slop maybe too much clearance or wear between ring and pinion gears after years and years of use. Our shop Bronco did that right before the ring gear gave up the ghost which left a bunch of trash in the housing thanks to the guy who drives it every day not saying anything while it was “clunking” every time he hit the gas. He no longer drives that one. I do.
Traction Lock rears require a small bottle of Ford Motorsports brand whale oil added to the lubricant. Using the gear oil marked “for Positraction rear axles” does no good. You must use a bottle of the Ford Motorsports Traction Lock Additive or it will do what yours is doing.
