Rear End locker noise

Ok i need some help. I was driving to school today and at about 25 mph i hear a huge loud pop sound. Now every few seconds there is a clunk sound coming from the rear. I did the grey wire mod a week and a half ago with no problems until now. I have no clue whats going on and it does not seem save to drive.

My truck is a 2001 toyota tacoma 4x4 TRD.

Any help is appreciated, thanks.

 

Broke a tooth of the ring gear maybe? The grey wire mod shouldn't have anything to do with it. Unless you have the rear locked with driving on the street?!

 

i didnt push the locker button or anything, just randomly driving down the road and POP! How can i check to see if it is a broken tooth?

 

could it be a u-joint problem? just throwing out ideas.

 

drift mode

i would assume you'd have to take it apart

 

if its a u-joint i'd assume it was your driveshaft and you wouldnt be able to move unless in 4x4 (ask me how i know )

 

Well to verify that its not a Ring, Pinion or Spider gear tooth. Pull the drain plug on the differential and see what falls out. If you pull the plug and it looks like these photos, then you can rule out the locker issue

For the record, this is what happens when a pinion bearing in the front Diff decides to seize up while driving 45 mph... Not a fun project!

 

If you broke a gear tooth, there will be pieces of it in the gear oil.

 

Sounds not good, i agree with draining the diff fluid and checking for shrapnel, if it were a u joint you'd have a shit ton of vibes
