Hey guys my aluminum front diff housing is cracked (again) so im planning to upgrade to a steel housing this time. So I figure this would be the ideal time to add a front locker if thats what I decide to do.

I've been reading up on here and found some conflicting info regarding the effect of a locking diff on the axles.  Some have said that it is easier on the axles because there is not the effect of the diff slipping then suddenly catching.  Some have said the opposite.

I would love to hear people's opinions about whether or not the diff lock could save axles or break more of them or neither. I would also be interested if anyone can reccomend a locker, also is a pinion collar helpful even with a steel housing? Any other food for thought would be welcome.  Thanks.

what kind of locker?, slip/ratchett, Sprague, or full lock up like ARB ?

I haven't decided what type. Probably not ARB just due to the price. I guess thats what I'm trying to figure out.  If I decide that a locker will cause more cv breakage then I will leave it open but since I'm going to use a steel housing I think a locker is worth considering.  Any thoughts?

The axles will become a weak link with any locker, locked up a locker is a locker, with upgrading the housing and third, it is one of the parts not upgraded yet, LOL. But if you dont push the angles of the driveshafts too much with suspension drop they should do ok.

I know several guys who are locked with aluminum housings and thirds and they have never broken anything and they only drive on logging roads and skid trails, transpo while logging. They are not out pushing/exploring the capabilities though with 29" AT's, LOL.

I have ARB lockers in my Tracker, 32" tires and stock aluminum front housings, though the mounts have been modified and I'm using a strap system I made up for the rear cross member mount. I do everything from sightseeing trails to rocks and ledges, and all kinds of obstacles. I've run blue/black trails and have accidentally taken some " buggy " runs at a few of the off road parks. I think if you have some LOW range gearing, that makes it easier on all the parts, axles included. The locker is a great traction aid, and I think your driving style has more to do with breakage than anything else.

Thanks for the input fellas.
