I have never had them before. Much more familiar with Detroits. I now have ARB's front and rear and have a few questions about their operation.

1. Do they unlock right away or do you have to drive a few feet to get them to unlock? I lock my rear in and drive a few feet and start to turn left in a circle. I can tell the rear is locked. While still turning I unlock it, but it continues to stay locked. I start driving straight and it still stays locked. As soon as I turn a bit to the right it will unlock. Is that normal operation?

2. As for the front I lock it in and as soon as I start driving I can't turn the wheel to the left. Infact as hard as I can, I try and hold the wheel straight, but it will force it right out of my hands hard to the right. I have to stop as the wheel is cranked all the way to the right and there is no way 3 guys are going to get it to go back to the left. What is up with that?

As far as your front issue, I have no idea on that. Maybe Keane has some info since he runs TOY axles. On the operation of the ARB, they will disengage as soon as they unload. If you stop and disengage them, they will normally unlock right away. Some times I have to back up to unload the gears. Never engage or disengage an ARB while there is force on them. This will cause premature failure of your clutch gear. I had a clutch gear go on my previous Dana 44. Now I come to a complete stop or put the tranny in neutral before I lock or unlock them (this was per ARB for warranty purposes)

That doesn't sound good to me at all. Something must be binding up. Maybe try jacking the front end up and engaging and disengaging to see how it acts. Since it's pulling to the right, I'd check for binding on the right. The wheel still spins right?

I don't have ARBs, but I do have a full front locker. I'd expect it to be much tougher to steer, but it should still be doable.

Thanks for the info. That sounds about par for the course for the rear. I found backing up sometimes helped. Probably works a lot easier on dirt as there might be more slip to help it unload and unlock quicker.

Exactly...even with the front locked it should be able to be steered. After trying it in the school parking lot I came home and put the front on jackstands and played around with it. Disengaged one wheel spun forwards while the other went back. When engaged the both spun the same direction. Seemed to work like it should.

I am going to call marlin tomorrow and speak with them since I bought it complete from them. Maybe they can give me a few ideas on there to start looking.

Did you put in Longfields? Sometimes you have to grind the knuckle to get them to spin right. Maybe it's binding up when it's under load? :dunno:

I think you're on the right track with Marlin!

I can't afford Longfields yet. Just have the stock shafts. I thought it might have been something along those lines where one hub was engaged and the other wasn't, but it couldn't be that simple 😥

This may be a dumb question but are both front tires the same size and aired up to the same pressure?

Yea....everything is cool with the tires.

I drove it a lot more again yesterday evening and I am starting to lean towards a problem with the left hub. I notice when I back out of my driveway that left front seems to be binding up like being in 4wd on the street when actually in 2wd. Its leaving a black tire trail when I turn and when I turn tighter you can hear and feel the tire skipping across the pavement.

Also going around corners you can hear it chirping. Its almost like its locked in when the hub is in the "free" position and unlocked when turned to the "lock" position. Though on the jack stands it behaves like it should when I lock and unlock everything.

I have a few other tests planned for this moring and might give me a better idea of whats going on.

I have a spare hub if you want to try it. Of course, Grass Valley may not be the most convenient place to get parts from. 😀

This is a pretty good article on how to rebuild them:

Well I got it figured out. Just a stupid mistake on my part. I was going to swap everything from knuckles out from one side to the next, so I took the wheels off the front and started looking at how the steering was working and this is what I saw. Anybody else see the problem? 😀

I'm a bit confused...but it looks like you've got no space between the spring and the tie rod/drag link. Not sure why that would be different with the locker on vs. off though.

There is actually enough room between the springs, but the tie rod and drag link are in the wrong holes on the two hole arm. They should be reversed. Turned one way they were ok, but the other way they were hitting each other. Plus with one tie rod end out farther than the other it would turn that wheel less resulting in one wheel turning more than the other making one scrub across the ground making marks and squealing.

I put the tie rod and drag link in the proper holes, did a quick alignment and it drives so much nicer. It does drive better with the ARB engaged now, but still is hard to turn since everything is so locked together with that ARB. I believe the Detroit I am used to gives a little more.

I'm glad I wasn't the only one. I thought the tie rod and drag link looked aweful close but couldn't tell why.
