Well I put an Aussie in my 2nd gen about 2 months ago. It drives me nuts though. Every time I idle through a sharp corner it starts fidgiding, clanking, and unlocks and locks and unlocks and locks as I go through the corner, jerking the truck all over like I dont know how to drive a stick. I had Detroits in my old yota, and never had that problem..

Anyone had that problem>? is it a "deal with it" or could something be wrong with mine?
I wouldn't have got an aussie if I would have known it would be like this! I would have got another detroit

thanks

Chris

 

Hmmmm.

Everyone thinks I'm a dick when I say that autolockers have their drawbacks. Lunchbox is even worse.

Here it is folks: yes you really do notice them.

Gotta get used to it. lots nosier than a Detroit.

 

I have an Aussie in the front, and really only engage 4WD on the trails... so any negative traits I have not noticed.

I do know when I did the install there is a pretty minimal amount of tolerance acceptable between the plates. You might verify that you are within spec. Of course, you'd have to pull the diff to do that.

Most likely you'll find everything setup right and just deal with the nuances of such a locker... but it might be worth a shot to check.

 

I have V6 Lockrights front and rear in my truck and mine does click and buck at times. I run a heavier oil (85W-140) and it helps to quiet it down noticably.

 

i run the loc rite in the rear and it is'nt that bad, try coasting through turns more

Oh, and wait til somebody else drives your truck for the first time ... hopefully they listen to you and don't put it in the wall, other lane, ditch ...

 

What exactly are you doing when you have this problem? I'm another Loc-right guy but the basic design and function is the same. Also I take it from your post that you have a manual tranny. I've "heard" that the lunchboxers are supposed to be more forgiving with an AT but I don't know anything about that.

When I'm driving at regular street speeds I try to come up to a turn with a decent amount of speed, then depress the clutch pedal and coast through the turn until I have the wheels straight again then re-engage the clutch. Then I just hear the thing ratcheting through the turn. If I have to turn from a stop (redlight/stop sign) I try to pull out smoothly with gentle but consistent acceleration. That generally works fine with big arching left turns but usually get a little chirp with tight right turns. The only real trouble I have is when I occasionally get stuck going through a turn at the wrong speed and I have to switch from coast to acceleration mid-way through. Thats when I get the manners you're describing, but it's really rare. And the locker kicks a$$ on the trail so there is no way I'm ditching it.

 

OK thanks guys. yeah its only when I give it just enough gas to maintain my speed through the corners. if i let off the gas or gas it it drives fine.. just never had that with my detroit (never had a lunchbox)

and yeah everything should be in spec... (was when I installed it)

Ill just deal. Maybe try some thicker oil... cant hurt right?? theres no way I would go open diff, love having a locker

 

my fiance drives mine a lot, she doesnt mind too much. (she has a 4runner too)

its not that bad anyway, haha

 

The Aussie Locker directions say you must use a thicker oil, 140W IIRC.

I've had rear luchboxes and normally didn't have such a problem unless I did the wrong thing while driving.

One factor that is causing the issue is spring wrap. A locker will tend to cause more spring wrap. I have improved the problem by replacing leaf weak springs with good ones with an extra leaf.

The locker is also sending the power to the inside wheel while turning (while the outside wheel is temporarily disconnected, or "freewheeling"). This also contributes to the problem, because while the vehicle is bucking the inside wheel is also trying to push and pull the vehicle toward the inside and outside of the turn. Steady throttle or having the clutch disengaged cures this.

Another is the extra backlash (play) in the locker itself that a locker needs to operate properly (I think a Detroit has less backlash). I have noticed that the No Slip, which has extra springs to dampen backlash, very rarely does what you describe like the Lock Right does (which is basically identical to the Aussie), which doesn't have those extra springs. So despite misconceptions about lunchbox lockers, not all are created equal, with the No Slip being the smoothest of them (about 80% smoother than a Lock Right).

I also have noticed that being geared too high for the size of the tires can make the problem worse. I went to lower gears, and that somewhat improved the behavior while on the throttle while making a turn under power, because the engine doesn't need to lug as much while going slow, which can cause bucking.

 

ooooh. Never saw that. THanks

Ill switch it out


thanks for the info william.. I'll probably just stick with it but If i get another toy maybe ill llook into a no slip

 

Dude, that is a great picture!! You have to submit that for the next calendar.

 

i have a lockrite in my truck and sometimes i get what you are talking about, i figure its just how the lunchbox lockers are,awesome on the trail but not so perfect on the street.

 

It's really an easy fix. Don't coast through sharp turns!!!! Either clutch it or gas it. It's enough to drive you banannas if you don't adapt your driving to the locker, my does it all the time. I still love it. Just be glad you don't have an automatic, ouch. Makes driving much more of a challenge, kinda puts the skill back into it.

FYI. If you would have research lockers before you had it installed you would have known about this before.

 

That's fine if you ride the clutch as needed, which allows the clutch to slip (causing the clutch to sort of act the way torque converter does in an automatic). And gassing it takes up all of the slack (backlash) that the drivetrain has, eliminating the effect of the extra backlash that a locker has on the drivetrain.

But sometimes you find yourself in a situation where you must coast.

An automatic, due to the torque converter, absorbs shock loads. It can act like a slipping clutch. This reduces the effect of a locker instead of making it worse. So an automatic locker should act better with an automatic transmission.

By the way, the thicker oil is supposed to help dampen the action of the locker. But I never really noticed any difference. But you might hear and feel a difference, so it wouldn't hurt to try.

And notanymore, not all automatic lockers are the same. The No slip is better than the rest, with much better manners and more durability.

 

I've got them F&R. I love them. I honestly don't mind the drawbacks you described for the $500 ($250 vs $500 x2) I saved over Detroits. Pretty much paid for my 4.7 gears.

 

exactly. I had 2 detroits and 5.29s in my 85, never had the lurchy bucking through corners. I can't really complain for the money though on the aussie I guess
