I'm wanting to put a locker in my stock X. So I'm trying find the best kind for what I do. How many miles can you get out of an ARB locker bfore you have to start worrying about replacing the seals or anything else in it?

 

I know people around here who have had ARB's installed on their rigs for almost 10 years that have had absolutely no trouble, maybe they had to replace an air line or something but thats a normal wear and tear thing anyway. As long as whoever installs your locker does it properly you shouldnt have an issue, your axles would probably fail before the locker does.

 

Thank's for the info. One of my problems is finding someone to install. I've got the tools to do it myself; but I don't know if I'm good enough.

 

Install could be done on your own, but from what I read, a case spreader is needed to ensure the bearing preload is set correctly. That tool is kind of expensive.

For backlash, a dial indicator / base and caliper are worth owning for other auto work.

 

Keep in mind that ARB wont warranty a locker if it isnt installed using a case spreader and 90% of ARB locker failures are due to installation error. If you're doubting your capability to do it you should probably look around for a local shop with decent rates that have experience installing gears, lockers etc. Most places will buy the parts and pieces needed for the install direct from manufacturer at their cost and mark it up anywhere from 15% - 30% then sell it to you, if you opt to use a shop to do the install make sure they're cool with you buying everything, it'll save you a nice little chunk of change especially if you shop around.

 

I've rebuilt ford and chevy diffs. But have never heard of a case spreader. What does it look like. I have all the rest of the tools needed.

 

It bolts onto the diff cover holes and exerts side pressure to spread the bearing seats apart so the correct shims can be installed for the correct load. I have the ARB and the OXlocker and I prefer the OX. No internal air lines or seals to worry about. I actuate the OX with air tapped into my CO2 tank. Simple and IMO is stronger than the ARB. The ARB is a good proven lock, but I think the OX is a bit better .

 

My Jeep is a daily driver so don't need much in ther. I just wanted something for when I go to Colorado to help out a little bit.

 

I'm no expert on lockers by any means, but sounds like you'd be wasting a lot of money on an ARB. Assuming you're on a budget, you might want to look into an Aussie locker, it's a lot cheaper. Plus that seems more up your alley.

 

You maybe right. I'm hate to set there while one wheel is spining and the other is not. I've got lockers front and rear in my 74 Ford. I guess I'm just spoiled to it.
