Locking Rear end
Hey guys, being new to the truck tuning scene i have a quick one for you. I have an early 99 PSD 250. I was wondering if any one out there makes a rear end that is locking (both wheels spin even if taking turns). Right now if i pull out of my street only one tire spins and tere fore tread is wearing down on that one side. So id rather it be like my mustand and whip teh rear end out a little bit.
any suggestions or name brands to check out?
Thanks
-dave

Do you have a limited slip rear axle now? It may just need the fluid changed and additive put in? I know it's not the same as a true locker but when i floor mine going around a corner it will kick the rear end out and all i have is factory limited slip 3.73 rear end.

That is a locking differential. Not a limited slip. There is a difference. Limited slips generally use clutches, but sometimes gears, to allow them to slip, but generally keeps them together. Clutches wear out and do what mine do, let you spin the tire by hand. A limited slip in good shape, you cannot turn the wheels by hand while the transmixer is in park. Now a locking differential is different. They require torque to be applied on the input (pinion) and wheel slip to then engage, and lock the two wheels together. Generally they stay locked untill you release torque from the input or go passed a governed speed, which they automatically unlock.

Detroits are great but I have had to learn to drive all over again when I had one in my off roader. Winter roads are crazy when you lock up the rear. If you lock it up you should bare no expence and get a good one or you might end up dragging a tire when you turn like with a spool. Some of the cheaper ones are noisy and clunk real bad when you turn. They seem to wear out tires quick too if you are heavy on the throttle through corners. A good Auburn Gear limited might be better for street applications.

I have also heard some negatives about Auburns, BUT I have an Auburn Pro in my '93 mustang (novi 2k 347 5speed 4.10s) with over 37k on the diff & its rock solid. I have Detroit locker (rear) & Trutrack (front) in my '84 Toyota trail rig & they work great, though the rear does chatter when you make tight turns on pavement.
