Lockers

[blackdiamond]

Blackdiamond, how much does your 4runner weigh? I've been reading into the debate on selectable verses non-selectable.

I don't honestly know, but based on the curb weight I would guess under 3,500 lbs. I have larger tires, an extra t-case, bumpers, sliders, crossmember, winch with rope, and not much else.

In regard to ARB's, I've heard that you have to run a good gear oil with them and zero water can get in the diff. If it does you need to change the oil ASAP and you should be good to go for a long time. An also to make sure your beather isn't plugged. Not saying problems can't arise, as with anything it can fail but that taking care of it is essential.

I ran cheap gear oil and changed it once after break in for 10 years. Only changed it after a seal finally failed after the truck sat for a year and a half. I will be running decent oil in my new ones here in a few months. We will see how it goes

Run that sweet pink stuff.

Should never run cheap gear oil, but it isn't like you have to spring for royal purple or other synthetic diff oil.

If you run breather lines, something all trail rigs should have, you should never get any water into the diff

Not aware of the weight being part of the debate, what are the issues?

It is fascinating to me the amount of people who are happy with their Truetracs. I wonder if it is people who have never experienced a real locker before?  I hated my Truetrac and advise people against them all the time. For the money you could get so many better options.

I had a Detroit in my first truck with arb front and it worked great. Love having a full locker. But it also depends alot on how your suspension works. If your pulling tires off the ground all the time then yes the Tru Trac may not engage the way you want, but I hardly pull a tire off the ground and with duals I hardly even use my front locker. Thing does amazing, but I will say my Tru Trac has slipped up a few times. I just got my hands on a 14 bolt and will be installing an arb for sure in the rear, but I will recommend a Tru Trac to people depending on application and use

Oh it just seemed like when people mentioned that they run auto lockers the ones with a heavier rig didn'tond them as much in bad weather. At least that's what I gathered

I think the key to a street driven automatic lockers is being smooth. There is definitely more play between the drive and coast side of things and it's a more forceful transition. More weight and an automatic transmission both have potential to soften the transitions.  If you can't drive smoothly then an automatic locker may not be a good choice.

It was just the sta-lube gear oil. Ran it for years with no issues

Didn't think sta-lube was considered cheap,   I think the last stuff I used was valvoline.

Sta-Lube containers look rather generic but I think it's pretty good stuff.  Not real cheap.  My old timer parts guy swears by it.  I got the GL-4 for my trans and t-case this year. I was going to get redline but my guy couldn't order it.  Trans shifts nicer and is quitter than the GL-5 I had in there, so the Sta-Lube must be better than average anyway.

I would guess the GL-4 stuff should perform great in the transmission.
