New Guy with Diff question. To Lock or Not??

Good afternoon everyone,
Well I've been out of the Jeep game for the last eight years and Just picked up a 94 YJ for a Ranch Jeep. I bought a plain jane S with the 2.5L, 5 speed with 4:10 diffs, the rears a 35 with a traclock upgraded shafts, running BFG/AT235x75x15.
I found out a few weeks ago the traclock is not traclocking at all. I changed out the rear diff and refilled with new and added the friction modifier and its still not working properly.
Since Im only using around the ranch with the occasional run to the feed store and DQ I was thinking of replacing the traclock with a lunch box locker.
Now my questions, What's a good locker and one that's an easy install I can do my self, and other than a locker any good options for the front?
I know all about the weakness of the 35 but with the small tires and low HP I figure ill be ok.
I look forward to hearing some input.


Thanks and Stay Safe everyone.

aussie locker is dependable, fairly cheap and easy to install. In my experience it seems to help more in the front and avoids some of the risk from locking the D35

I would look into rebuilding the trac loc in the rear. Probably just worn clutches and I doubt it'd cost more than about $60 to replace them. I know you said you'll barely drive it on the road but I generally discourage people from putting a lunchbox locker in the rear especially with a manual transmission. The road manners are terrible and every time you shift, the jeep will dart left or right. There are lots of people who learn to live with it. After driving like that once, I refused to do that regularly. As an FYI... friction modifier is used to ease the engagement with limited slip diffs meaning that it makes the clutches slip more. Without friction modifier, the clutches will be a bit more grabby.

An Aussie, Spartan, or Lokka lunchbox locker for the front would be a good, easy upgrade and you'll barely even know it's there until you engage 4wd.

Dana 35s don't have a good track record for being locked, but a lot of that may be due to bigger tires and wheeling style. With a 4 banger you might be ok.

Any locker you can 'do yourself' IMHO would be an auto lunchbox type. From reviews, the Aussie is prolly your best bet. I had a, IMO, a bullet proof power trax no slip, but they are pricey. Any full locker and even a Detroit will require re-setting gears.

I'm not a fan of the Spartan, pops pretty gnarly. Lockrite I think is the best, just my 2 cents. And I'd only put a lunch box in the front. Full case Grizzly for the rear, behaves great.

Trying to weld has honed my grinding skills

interesting thread.

carry on gents

Stop whining about the 'ride' - If your YJ ain't wrangling your soul free, then might I suggest you buy a stationwagon... at least you can fit all your bull**** in the back.

I installed Detroit Tru Tracs in my freinds YJ. Excellent traction and great street manners and no special lubricants. The downside is the cost and it requires swapping out the differential. Trac loks tend to slip a lot because preload pressure on the clutch plates is relatively low to make them street friendly. They wear out relatively fast.

Rebuild clutches in the rear and lunch box up front. You should be able to do both for less than $300.

I know this is off topic from the original thread but you should at least look at the OX air locker. Basically the same price except you get a super beefy diff cover, install is a little easier, and for $25 more you can get a "drive-away lock" that in 5 minutes will allow you to lock your diff if you have any issues with your air system or lines.

Another vote for a rebuild. Very affordable and probably suits a ranch truck just fine.

With that being said though, lots of good suggestions here.

If you cannot fix it with a hammer then it has to be an electrical problem.

Good point.

Just looked into them. Actually cheaper but does not include an actuator, though the cover and the provision for it does eliminate the need to drill through the pumpkin.

Sorry for the mini hi-Jack.

A lunchbox locker is not recommended for the D35 they are fine in the D30. Rebuild the LSD you have and add 27 spline 1541H axles or add a Eaton TruTrac with 27 spline 1541H shafts or bite the bullet and add a full case locker that accepts 30 spline shafts and 1541H shafts.
