Eaton Detroit Truetrac LSD

[19Bluecrew]

So, Eaton is offering a limited slip. Anybody gone down this road yet. I am very interested.

Damn if only install wasn't such a PITA.

And you have to buy a new ring and pinion since our ring gear is welded to the carrier.

Thanks to Ford's "Better Idea" many have not bothered to do the LSD or Locker swap for the rear axle. That said if you go for the Detroit True Trac, understand that it is really only good for street use. I say this because it will act just like an open diff if one of the wheels is in the air.

Yeah, I saw that in the Eaton notes. More expense for no reason. Millions of ring gears bolted on with no problem: "let's weld it on!" ?‍

Do you know why Ford did that? Because bolting the ring gear on was too hard

I'm strictly a street driver, so that's not an issue. I would really enjoy being able to accelerate from a stop without traction control kicking in. Southern California is rotten with sports cars, and electric vehicles that are crazy quick. I'm just trying to survive!

It has to do with production time . Ford does not manufacture the rear axel ( or a lot of the parts) . Car makers have become assemblers. Pushing venders to meet parts spec at lower and lower cost !

And yet it probably cost more or about the same to weld the ring gear to the diff versus bolting the ring gear to the diff. If I'm not mistaken Ford went to Dana for most of their axles and simply chose to do this. I'm sure some engineer over at Dana gave him one weird look and asked why. Probably after was probably thrown into a dark room and locked away.

It looks like they only offer the E-locker for the front.

I would really like to get the TrueTrac there.

Unless you rock crawl (no real rock crawling in north GA, just mud and forestry service roads) the TrueTrac is a great off road differential, particularly in mud.

I have the TrueTrac in the rear and the Spartan helical (Spartan version of the same thing) in the front of my Jeep and have a running bet with my Jeep buddies that have Rubicons and are always trying to get me to get a Rubicon as well.

If we ever encounter a trail where my helicals are unable to complete the obstacle and the Rubicons navigate it easily, I'll get a Rubicon.

It hasn't happened yet.

Also, my Bronco has the Detroit Locker in the rear and the TrueTrac in the front and this is a dynamite combo, excepting the sometimes squirrelly street manners of my Detroit in the rear.

You don't necessarily have to be rock crawling to simply lift a wheel though. I can't speak for back east but I have been to a few places here in Colorado where I wasn't rock crawling and I was lifting a wheel a few times. It happened more with the Pathfinder thanks to the short wheel base(and no so flexible front end) and made things interesting to say the least

While it's not uncommon to lift a wheel in our area, it is VERY uncommon to lift one on each end at the same time.

There are almost always 3 tires on the ground so forward momentum isn't a problem.

That is true for the most part but mogul like surfaces can get the third tire very light contact. I have Torsen differentials (very much like Truetrac) on the front and rear of my 02 Ranger and I like the way they work off-road. I spend about 4 weeks every year in some pretty rough wilderness areas without any issues that keep me from going forward.

I think a locked differential will give the best traction but the convenience of not having to lock and unlock the differential makes helical type LSD very desirable. When I had just the Torsen in the rear, had to use my parking brake a few times to improve traction. Installing the Torsen in the front eliminated having to do that.

I believe a locked rear differential in the rear with a helical LSD in the front would provide better traction in extreme cases but 99% of the time helical LSD front and rear would be just as good. I am not sure I would want to spend the money to convert the rear differential of a 5G Ranger to a Truetrac, but adding the Truetrac to the front would be worth it in my opinion.

The robot assembler /welder is faster .
