Title: Lockers
Post by: RichT on July 30, 2005, 11:25:16 AM
Hi

When I go to 4.10 R&P I'll loose the standard rear LSD, any advice on replacement? Looking at Powertrax and Aussie Locker for front and rear, any thoughts/advice appreciated. I don't want air lockers.

Cheers

Richard

You can't put an Aussie or NoSlip in the front of a TJ if you still want to be able to steer. You'll have to use a Truetrac or similar if you don't want air lockers.

Hi

The Torquemaster Aussie Locker will go in the front Dana 30, see http://www.4x4xplor.com/tj.html (http://www.4x4xplor.com/tj.html).

The Powertrax No-Slip is designed for use in the front Dana 30 - see www.quadratec.com (http://www.quadratec.com) P/N 16104.102, and rear Dana 44 - see Quadratec P/N 16104.109.

Both are advertised as extremely quiet in operation and suitable for 'extreme heavy duty' use.

Cheers

They'll fit in ok but you could find yourself going in a straight line when you don't want to with one in the front end as well as the rear. That's one of the reasons behind being to turn ARBs on only when really required.
Don't get me wrong, I put a NoSlip in the back of my YJ and it worked great, but you have to get used to being very careful on the gas on bends, especially in the wet, otherwise the rear end will try to shove you off in a straight line at an akward moment.

Hi Mike

The blurb says that the locker performs like an open diff on road and automatically transfers drive to the wheel with traction when off-road, is this a load of BS? Don't want to spend my cash on something that doesn't work.

Cheers

It works ok, and they are pretty quiet, but you will certainly know it's there when you drive it. I had to modify my driving style somewhat, in the YJ, powering around wet roundabouts becomes a definite no-no for example even in a 2.5. The short wheelbase of the Wrangler makes a lot of difference, I've driven an XJ with a Detroit Locker, which is a similar device but comes as a complete diff carrier, and it's hardly noticable on a longer wheelbase Jeep.
The NoSlips and Aussie Lockers are definitely the cheapest option, as, apart from the purchase price, you can fit one yourself with the diff in situ in a couple of hours, but if you're already paying someone else to regear your axles, you might be as well to fit an ARB or TrueTrac if you can afford the extra few hundred bucks.
Personally I'm tight, so will probably stick a NoSlip in the XJ at some point unless some kind of mega bargain alternative comes along in the meantime.

One thing you must take into consideration when reading any review of lockers in the US is the type of terrain that prevails. Death Valley and the surrounding area is fairly dry if Discovery channel is correct. :shock:

Front axle options for UK froading are:

ARB, OX etc
Detroit Tru Trac

If you cant find the budget for one of these then leave it open till you can.

If you're going to put a self locking locker in the front, make sure you've got free-wheeling hubs fitted. You'll be ok then. If you haven't, and the locker locks, you're going to be surprised, especially on road! By the way, and excuse my ignorance, why will you lose the LSD by changing the ring and pinion? Surely the new crownwheel will bolt onto your current LSD and you'll be able to keep it? It does on ours.

You lose the LSD because you need to change the carrier. There are two carrier sizes for all Jeep axles if you want to change the ratio beyond certain values you'll need to change the carrier too.
Common Dana ratio breaks are:
Dana 30 3.54 down / 3.73 up
Dana 35 3.31 down / 3.55 up
Dana 44 3.73 down / 3.92 up

Right, now I understand. Our carrier is standard across the ratios so we just have to change the crownwheel. I'd forgotten just how many different axles Jeep uses!

Hi

Thank's for all the input.

So - Do I need freewheeling hubs if I get a Detroit Tru Trac for the front?

Cheers

No freewheel hubs required. The true trac has no effect whatsoever on normal driving conditions and will appear invisible until slippage occurs.

Not experienced any onroad problems with the Truetracs, got front & rear.  Offroad performance is good as well.  As Bubba said they may require a brake dab on the odd occasion as they need to have some grip on both wheels to work, so if you already have a paw in the air the truetrac needs some drag from the brakes to engage.
