Topic: lock right ?

[olivedrab85]

So I put a lock right in my front diff (5.29's, 30 splines, 85 front axle) When I had it on the lift i locked in the hubs and spun a tire, just one spun and clicked. Is this normal, do they work off the pinion spinning rather than each single axle? My detroit would spin both all the time. Just want to make sure that this isn't broken before the round up.  thanks

i believe that is normal

[Hottrod81]

That's normal.  That's why they tend to not work well in the rear because they will release at odd times.

i would much rather have a truetrac  than a lockright  , but thats just me

[Hottrod81]

Same here

I've only wheeled with one guy running a Truetrac in the front, but it was worthless. He was running through a rock garden and he might as well have had an open diff. I, and several friends, have run LockRight's in the front (one was an Aussie) and have had zero issues with them. I would use one again in the front with no questions. I guarantee I'll never run a Truetrac, ever. But, to each his own.

Thanks.  I'll run it till i go selectable.

if my truck was a "rock crawler"  and nothing else and i had endless funds to buy replacement birfs  i would run a elocker or arb in the front
but since its NOT  and is used as a general purpose offroader  and work truck  and i need dependability over  "I gotta climb that rock because jim bob did"   I'll stay either open  or a truetrac
but yea  "to each his own"

Ya know, I wasn't thinking about the birfs (I've mentioned several times that I'm new to Toyotas), but now that I'm thinking about them, I definately understand where you're coming from on waiting for a selectable. ARB's something I think I'll add to my wish list for the future.

Run E-locker's front and rear.  I do

My lockrite did the same thing when I had my truck on a lift. I figured it was broke and pulled the frontend apart It was fine. I guess when a lockright breaks(the pins) it turns into a spool. Not a bad way to break a locker if you ask me. They do some quirky stuff but if you like to play in the rocks they're  fine. Open or limited slip in the front is fine for the more practical uses of 4WD. A tru-trac is no good for rocks, muddy trails in a hunting rig they're great. I run a lokrite front and detroit rear.I like it. AS far as birfs, with a locker up front you should upgrade 'em(30 spline longs). The first time I did the 'con I had 35's, a lok-rite up front with stock birfs and a trutrac rear. I also went with a cj5 and a cj7 and I didn't bob my longbed yet. Of course the jeepers (with tera 60's) loaded my underequiped truck to the point of where the front end was pointing to the sky. I looked like I was goin' to the dump. I did'nt break. Granted, I was driving with alot of concern for breaking parts but the frontend was doin' alot of traction duty and pullin' the truck over stuff. Maybe it was just luck.

i am expecting one soon ....even though i still have to find a truck to have it in

[hi on lux]

are these truetrac specific for front or rear or fits both?

That is normal, it works under load, its confusing but as long as it works when you need it.

probably be easier for youto find a samurai  over there

Lunch box lockers work like a non directional ratcheting mechanism adapted from Industrial machines. If you put the 2 inner halves together and look at the hole where the center pin goes you will see it is not round. It is built to have ramps on either side of the center pin. As the pinion turns the ring gear it in turn puts the torque to the carrier and the pin. In an open diff there would be spider gears but with a lunchbox these are replaced with the inner clutch dogs with the ramps that I described above. The pin pushes on the ramps forcing the inner dogs out locking  with the outer dogs which are splined to the axle. It take torque to make a lunchbox lock. Sitting on the lift and no torque applied the pins and springs keep the dogs apart enough to let them ratchet. What you experienced is normal, now go wheel and see if it works.
