LOST 4WD PLEASE HELP!!!!

[hidemylux]

Hi all, My worst fear just happened, heading up a challenging hill climb,nearly at the top then my 1kz 2001 started to violently bounce, BANG i have just lost 4wd. I have 2wd, low range, the 4wd light wont go but i can still drive in 2wd i thought it could be an axle or something in the transfer case,though the noise did come from the right side.When i push the 4wd button you can here a small electrical click but thats it any thoughts would be great.

Sounds like ya blew a cv. Ya still there? Not sure about the 4wd light or what you mean.

X 2 on the cv

As the others have said the bouncing probably created wheel spin and when the spinning wheel came down and suddenly stopped it blew your cv. Where did it happen?

[hidemylux]

Hi there, im from new zealand down the bottom of the south island, i had thought of a cv as well, the thing that has confused me is when i push the 4wd button on the stick the 4wd light symbol wont light up,but i still have low range,possibly a coincidence or could be related still drives fine in 2wd, no noises etc...

When you heard a "BANG" was that a mechanical/metal just sh#t itself bang or electrical 'pop' type bang?

[hidemylux]

Hey there, it was a loud metal bang not electrical i will try and post a video of it.

[hidemylux]

cant figure out video thing, nevermind

What do you mean by 4wd button.
Do you mean the hub lock button?
SR5 i assume.

I may be wrong, but I think the earlier models use to engage by using a vacumme in the diff and there is line under front driver guard with a little filter in it, I remeber it happining to me lost the filter on a bumpy hill climb and made an afull bang noise and lost the dash board light stuck a screw in the end if the tube and had 4x4 again and dash lights.

just a thought

[hidemylux]

yes the small button on the short lever,the hub engage button, thanks cuzo4x4 i will have a look and see if this is what it could be. my truck is a 2001 sr5

[cuzo4x4]

No prob, as I say it might be, I had a 2000 SR5 and was in the middle of creek crossing on the telegraph road when it happended.

made it to sashia (at the top somwere not sure I spelt it wright) in 2x4 and machanic said stick a screw in this line, and all was good.

PROBLEM SOLVED
jacked truck up and spun the front wheels front right cv is completely goosed, the light on the dash is now going too, the plug doesnt have a clip on it so with the shock loading it bounced off its perch,also gained another 10mm in lift once i emptied out the protection plate underneath.

Thanks for all input
