RR DIF LOCK

i have a '99 tacoma pre-runner 3.4 Liter V6 2 wheel drive that has the rear differential locker. i haven't used it in ages and when I try to engage it the light just blinks and blinks. I can't find any info on how to trouble shoot it or fix it. any advise would be appreciated..

 

Did you try backing up and turning from side to side?

 

Not sure if the autos have to be in neutral or park when engaging the diff lock. Try both and see if either one works.

 

did circles at 5 mph right to left and left to right both forward and in reverse...still blinking only.

anything else i can do? oil? lubricant? where is the RR DIFF located?

 

are you in 4lo because you have to be in 4lo, unless you've done they grey wire mod, to engage the rear locker.

 

i have the automatic trans.

There used to be a label / sticket on the driver side door with full instructions. any body have a 99 taco that still has that (mine peeled off years ago.)

 

Thats what I was thinking...

OP~
The locker is part of your rear dif... When was the last time you changed the dif fluid?? Every once in a whil I have to wait a few minutes for it to engage... when it does engage, the "RR DIF"" light will go solid and if you have ABS that light wil kick on as well... Let me run out to my truck and take a pic for you of the instructions. I'm not sure if its different for 4WD's though?!

Here it is... Good Luck!

 

thank you! I am off to do circles and 3 point turns around my block. neighbors think im crazy today.

 

I would try and keep it off the pavement if you can.

 

someone needs to read a little slower so they pick up all the details.

I'm not sure when the last time it was changed out? Mabe during the last big service I had done?? I DIY now though and I want to learn. Is changing out RR DIF fluid sometime a rookie can do?
