Do i have a Locker?

I'm wondering what are symptoms of a locker?

Today i went into some deep snow (1 foot and few inches) and heard some clicking with the 4 hi engaged. I believed it was from the front diff. At first i did go into the snow with only 2 wd and there was no clicking but when i pulled to 4 hi and stepped on it that's when the clicking started and it was only when spinning tires and trying to turn.

Another thing is when i have the 4 hi or low engaged when i turn it feels like i the front wants to stop like there is a handbrake for the front tires that turns on and off /pulses but when the tires are straight it's just normal and doesnt pulse at all.

Thanks in advance

When you are in 4wd does only 1 tire spin at times when the other is hung up? Or do they both spin equally?

I really dont have an answer for you since there are no trails here in chicago that i know off so i cant experiment but when i'm sharply turning with 4wd on the front tires try to stop i'm guessing because the outside tire is spinning faster than the inside and the ¿locker? is trying to fix that? Any one out there without a front locker does your jeep turn smoothly with 4wd on? Mine turns on steps. It tries to stop when i turn.

You are right that in 4wd your front will seem to bind up some especially if you are on pavement while doing this.

You probably do not have a locker. It's typcal for the front end to buck while in 4wd.

If you had a lunchbox locker I'm under the impression you'd hear it click whether the 4x4 was engaged or not.

I'm not locked up front, but I got the same pulsing when it snowed here and I pulled into the parking lot where I live. I think it was just the pavement.

cool thanks. Thats correct its on pavement when it tries to stop.

I thought i'd ask since yestuday when i went into the deep snow head first and when i tried to do a 180 to get out it started clicking while i was turning. i was going for more than 180 but it was way too much snow for donuts so i ended up turning around and getting out.

I was worried too at first, but then I thought about it and it only happened around full turn when i was trying to cut it into a parking space. Mine never clicked, but the wheel would cut back and forth. I put back in 2hi and it stopped

Can't you put the front end up on jack stands and spin one tire by hand and see which way the other tire turns? Oppisite direction=no locker, same direction=locker?

the best way to find out is too pull the diff cover and look ...

rear is probably a trac-loc LSD ... and they dont work at all

as stated its normal for the front end to buck while in 4WD on pavement ....

another way to check and see if you have a locker is to jack both front tires off the ground, have a firend hold one tire and you spin the other ... or leave on tire hanging with no one holding it and the turn the other one (if they spin in opposite directions, then you dont have a locker)

but if your jeep is stock, and you havent put a locker in it, then you wont have one ...

and the clicking could be a bad thing ... pull the cover and see whats going on

diff oil is easy to change .... lossen all of the bolts slightly ... remove the lower half of the bolts and pry the cover off to drain the oil into a drain pan you placed below the diff ... remove the remaining bolts, pry off the cover, clean up the mating surface on both the axle and the diff cover ... apply a liberal amount of RTV to the cover (wait no more than 5 minutes after you put the RTV on the cover ... it will setup quickly and not seal) put on the cover and tighten the bolts to the specifications .... preferable, let the RTV set up for an hour before you add the diff fluid ... i never wait and never have had problems ...

i always fill the diff until it seeps out of the fill hole on the cover ....

as far as lube reccomendations ... dont skimp ... get synthetic

for the rear, read the label on the gear oil and see if you need to add friction modifier or if it already has it in it (only for limited slip differentials ... your rear might be an LSD ... if it is, it will have a tag bolted onto the cover telling you that you need to add Friction modifier)

80-90 weight is reccomended, 75-140 weight for heavy use / towing

mobil 1 is good, and so is Valvoline SynPower ....

i run royal purple, though ... works a little better for my application
