Digs!

I was climbing a rock and I needed to pivot the front end to the left w/o moving forward so I unlocked my T-case, e-brake on, and locked up the front axle and was able to do so. However, this was not enough as I now needed the rear to pivot to the right which was not possible. Now to do a rear digs I need to lock the front end some how and the only way I can think of is to use front line lock like race cars or add a front e brake some how but my question is how would the t-case handle this? Would it be ok, or am I going to break my t-case? And no, double stick Atlas is not what I'm looking for

Youssef,

If you've swaped out teh stock 2 pin in the center diff to the solid cross (got mine from JM), then you should be ok. The LT230 is fabulous, I have yet to break it.

I was in the same scenario and I simple locked the front (I over-rode the ARB wiring to lock the front alone) and had my left foot onthe brake while I was romping on the gas for the rear to slide out...not GREAT, but its something that worked...

If you're looking for hardcore line-locks, best bet is Pirate 4x4

Yousef was the back unlocked? If not I think it would pivot easier.

What about making a small hydro disc brake for the front output of the transfer case? That would allow you to do rear digs the same way you do front digs

Should not be that hard to make since most of the parts would be off the shelf other than a few brackets and the disc. Here are a few examples of rear mounted transfer case disc brake setups.

I will have a look at the spare tcase I have sitting on the bench and see if I can come up with a few more ideas for you

It is pretty simple. You can run a manual handle and split the brakes between the front and rear. You can PM Pendy who has the setup in his rig. Or better, mod the t-case to shut down between front a rear. Or, what I do, unlock my front hubs for rear wheel only.

Dave L we kinda thought about that and came to the conclusion that there isn't very much room under there for a front disk on the T-case.

It is a tight area for sure and you would need to build a much smaller disc than the one people typically use but it might be possible. Just based on looking at my setup a 5 or 6 disc looks like it would clear and with the CDL unlocked that size should provide enough stopping power on the front drive shaft.

Anyhow just throwing ideas out there

I am thinking if you use a hydraulic caliper (or electric if there is such a thing) you could save some space since you would not have manual linkage to engage the brake just a hydro line (or wire). Mini Drag or Kart would be a good place to look for small calipers

Off to google and parts manuals I go

No, but then I can't lock the front when the rear is not locked. I need to do what Nadim did with his ARB's.

Quit jerking around and get a crawler box. I watched your futile diggs and know that a crawler box would have given you the control you needed for that obstacle. But seperate control of the lockers is important too.
The cutting brakes do work. But in crawler low I can point the tires and do the work.

My engine doesn't stall at altitude either.

Pendy Yousef

I must admit that after watching the green 90 with the crawler and TDI (kyle I think) my TDI/crawler lust had hit a new high

He would put that thing in gear and just idle up the obstacles

I'm so sorry to tell you this but crawler box will not improve the climb that I did as I will still end up in the same spot, plus I'm to good of a drive to be needing a crawler box. A crawler box is for guys with a small peeppy to make them feel good. I think I should call you my minion now is that how it's spelled?

Oh yeah, I think we both witnessed a TDI stall, no?

Dave, you are right that it was Kyle's truck with the TDI Crawler. There were actually a couple of them. They sure are nice...

Correct me if I'm smokin crack but with a differential in the t case the following statement should be true.
If you want front drive only Apply the parking brake a bit, out of Diff loc, If you want Rear Drive only apply the regular brakes out of diff loc..
Of course this means that we would need to have an engine strong enough to overpower the brakes by a slight amount..
