Help to identify what I have, locker question

[CJ007]

I just found these pictures of someones trac lok on jeepforum

If yours has the little clip that is on the left side of this pic beside the spider gear, that is the clutch pack. That will sit in a hole on each side that runs through the carrier. I couldn't see on your pic and its been a while but yours appears to be the same thickness and the carriers are thicker at that point to fit the packs down in.

I saw that people, with mustangs usually, replaced the clutches with carbon versions, which is why I ask.

Is there an auto locker that is good on both the street and light trail along with being simple to install?

Funny I found lots of similar mustang info some time ago. One was add an extra on each side and the other was flip them in a different direction to make them grip, I can't remember how they went but if you pull apart you need to watch as some are swirls and some are a different pattern.



If you are not wheeling much just leave those. If you are going to or don't like the Limited slip. You need a new carrier to put your ring on as the locker won't fit, even if you pull the packs out, it's too wide. You can prob find or buy a carier for $60 or free if lucky, the auto locker for a 20 is about 280 shipped. Ebay.

In your case, I would spend the money when ready and go with a selectable locker since you are on road often, short wheel base vehicles pop more with auto lockers than heavier full size.

Thanks for the replies. I will not do anything with that trac lok. I did a little research and changing the clutches is a big job and the trac lok isn't very good when new anyway.

Jeep Lockers - Locker Lowdown

Trac-Lok
Overview: The Trac-Lok is the OEM Limited slip differential offered in many vehicles-from early CJs from the mid-'70s up through XJs and some TJs. It uses stacks of friction discs that hold the spider gears from differentiating until enough torque is generated by the shafts to let them spin.

Street:*****
You'll think you're driving an open diff. The Trac-Lok is largely unnoticeable.

Off-road:*
You'll think you're driving an open diff. The Trac-Lok is largely unnoticeable. Unless it's new from the factory, don't expect anything but poor performance off-road from a Trac-Lok.

Good: It probably came in your Jeep from the factory. The unit can be rebuilt at home.

Bad: They require gear oil with a friction modifier and have wearable clutches inside. If you're planning on adding a lunchbox locker, you'll need to order a special application that will work with the clutch disc recess in the case. The recess inside of the case makes it slightly weaker than a standard open diff case.

It's difficult to weld into a spool if that's your thing. Basically, they don't work well, so don't waste your money. You're better off with an open diff.

I would probably get this one when I change.

Detroit Truetrac
Overview: The Truetrac is a geardriven Limited slip that requires no special friction modifiers to operate. That means the bozo at the Qwikee Lube can't destroy your spendy Limited slip by putting the wrong oil in. Under power, torque is sent to both tires unless there's an excessive amount of resistance on one.

Street:*****
The Truetrac is very unobtrusive on the street. When gassed in a corner or turn, you may feel the slightest pull, but there's no jerking or violent engagement of any sort. When under heavy throttle in a turn, the inside tire will bark a little, but not under normal driving conditions. Turning radius and tight maneuvers are totally unaffected.

Off-road:***1/2
The Truetrac offers near locker-like traction in all but the gnarliest terrain. We've found that modulating the brakes a bit can help keep one tire from spinning when the suspension is crossed up. You can't drive as elegantly in the rocks as you can with a spool or locker, but you'll have to work pretty hard to get stuck. In loose dirt twisties where you're lifting a tire, a Truetrac will almost always get you through.

Good: Great traction on- and off-road and can use straight 90W gear oil. They're moderately priced and great for front and rear applications.

Bad: There are a lot of little parts inside, so it's not as strong as most full-case lockers. Also, it doesn't offer as much traction as a locker or spool, and you may notice it (slightly) operating during some street driving.
