rr diff newbie

[t4r4life]

for the first time i used to rear diff lock today, just for the fun of it. man can you feel the difference! how fast can you go with the diff lock on? and what is the proper way to shift 4wd gear? because i stop the car put it in park and shift sometimes it works but some time it makes this grinding noise and doesnt work, oh yeah i have the push button shift knob for the 4wd.

not too sure about the diff lock, but I wouldnt engage it on dry pavement, only on loose surfaces.

As for shifting the transfer case, the vehicle must be at a complete stop, at idle and with the transmission in NEUTRAL, not park.

when you shift in to 4wd do you push down the 4wd button first?

the button is like a psudeo awd option when you shift it's 4x4-hi
they do difference things but i always push the button first just because it seems like it would be better moving through all of the selections instead of jumping to what i need, but that's my old school way of thinking and i have no mechanical evidence to back that up, it's just how it used to be on old 4x4's

and driving with the locker on is fine in any condition if you only follow one rule DO NOT TURN YOUR STEERING WHEEL, GO STRAIGHT ONLY, lot of people don't know or forget that drag race cars have a spool or a locker and are used on road all of the time, it is not the road surface that matters as much but the maneuvers you try to do with it locked, even stupid little ricers use lockers on the road every now and again for drifting comps but they blow stuff out alot as well from that, so for us best use of the locker is pretty described in the manual, you only need the locker when you are stuck or trying to go over a large obstacle, i can see no reason why you would be traveling faster then 5-10 mph with the locker engaged.

so if you use it as it was meant to be used you will always be engaging it off road on a slippery surface at low speeds, NO ONE drives a trial where a locker is required at 50mph....NO ONE...

Eric, you dont have a center diff lock/AWD thing like theizzardking says, he has a 99 when they made that, and LINY4runner he can engage 4wd whenever below 50mph.

meh just do the mod so u can use it in 2wd now thats fun !!!

 

[t4r4life]

using lockers on dry pavment with 2wd, is that bad for the car?

It is very hard on the axles and tires.

ic i think im going to do the blue/red wire mod when this freaking RAIN!!!! stops. is there anything bad about the mod, you know for the car?

I'm not familiar with the mod, but I would think that if it is done properly that it shouldn't hurt the vehicle. Just don't go driving around on the street with the diff locked all the time

 

[Elton H]

very easy mod what you wanna do is pop off the drivers side door sill plate then the kick panel look for a little black box now find the blue/red wire cut the wire then run a new wire from the plug side and find a spot to ground it

I am thinking about doing this mod also I have a question though. Do I want to be at a compete stop before locking the rear diff? and can I unlock it on the fly? Or do I need to stop before disengaging it?

I would suggest coming to a stop before locking it, I believe the factory setup won't allow it to engage at speeds over 5mph.

 

[t4r4life]

yep i try to do it on the fly it just flash and does nothing until i stop then the light went solid and man the diffrernce is instant

 

[RUNNINIT]

Thanks guys I'm gonna try and do this. Will report back with results

 

[Pikeman]

The main thing about turning the locker on is both tires need to be traveking the same speed. For example if you start to spin the tire and then decide to push the locker on it will break. Also if you are turning it will bind up and cause issues as it tries to engage.

 

[JohnsD90]

Also if you are turning it will bind up and cause issues as it tries to engage.

With turning it doesnt do well because, when you corner the outer wheel spins faster than the inner wheel and when you lock the axle then you run into issues.

 

[Pikeman]

John that is why I was saying not to turn it on while in a turn. Becasue of the wheel speed difference it will bind up if it does engage. Same thing if one side is spinning, both sides of the axle need to be going the same speed when you push the button.

 

[t4r4life]

just did the rr diff mod now, yeah when i turn the inner wheel is trying to spin but awesome mod if you wanna do some burn outs or sliding in the mud, very happy with the result.
