I had a ford LS in the back of one of my trucks, never once had a problem like you suggest. I have actually never ever heard that before. Even in my ARB manual it says having a locked diff will significantly increase control because the open diff randomly goes from side to side (their words not mine). So maybe it was a crappy LS and just wasn't really doing it's job. It's suppose to have both wheels spinning unless the difference in torque between the two wheels is too great, then it'll act as an open until the torque level goes below it's requirement. But I do respect your experiences and opinions. I am purely speaking about rear LS's....not front...I have no exerience with front LS's.

 

Hey there,

I just want to share some experience here. The only posi worth a damn off road is the powrloc for dana 60's, 70's and 80's. These actually work as intended and, if properly assembled, will lock both wheels under power to the point of twisting 35 spline axles. And they're great on the street. only chirping under light vehicles. I have a detroit in the 14 bolt under my ford. I drive it every day and it's awesome off road, but if I had to do it over, I would weld it up or spool it because it's very unpredictable and tends to be locked up most of the time. Driving with a locked up rear is not a big deal at all IMHO I don't see why people get so scared about chirping a tire around tight corners. My locker does it almost every corner anyway. Why in the world would you want to put an ARB in a ttb? I look at the purpose of having an open front diff as saving your shortside hub and knuckle joint because with the axle locked up you will blow it all the time. Even with a 300 6 if you do any sort of rough wheeling that requires an ARB. If I had a ttb and not a ton of money to blow on an ARB I would weld it up and use the longside hub locked off road until I really needed all 4 wheels and then lock in the shortside. The way I see an ARB- it's a device for the lazy with no talent to fab. Welding up the front axle does the same thing as installing an ARB if you have locking hubs. Don't say "But an ARB is an open diff when not locked" so what? I would rather have a welded up front axle with one blown hub than an open front diff. I also love it when people tell me their ARB compressor could also be onboard air. I can't think of a time I've needed onboard air anywhere. any rig going places that needed tires aired down we trailered in anyway so we didn't need to air the tires back up. Air tools? No.

 

No, wouldnt run air tools. But you and I use our trucks for two different purposes. What works for you doesn't necessarily work for me. So please don't judge or criticize. I don't want to have to lock and unlock a hub when I want full traction or not. That is a cheap and I think crappy way to do it. When I do something, I do it right. I also want to test what it's like to drive with a spool in the front w/ 1 hub unlocked and report my findings after the next snow storm. Driving with a locker in the rear might not be a big deal to you, but to others (and me) it is. Snow driving with one gets tricky as it becomes unpredictable, and I don't want to be chirping/wearing out my tires. I have an ARB in my front axle so I can run it as open until I need the extra traction. As long as you can drive with it you don't break anything.
