Clicking in rear drive or tires.need help

Hey I just heard clicking in my rear end.don't want to drive it.a few days ago I put lube gard limited slip supplement in.could that be the issue???WTF
need help!PS 01 trd tacom

 

Welcome to TW! Adding LSD additive will not cause any harm on a truck that does not need it, it will not cause clicking. How bad is the clicking? You check all your u-joints? Could you post a youtube video?

 

Well it's in first g.and I turn tires driveline won't spin.so it's gotta be the diff.I have an 87 can I swap out the spider ,are they compatible?

 

Yah u joints seem solid

 

Oh sorry and the clicking increases with the speed.I drove about 200 feet and turned back home.it's in air now.

 

Since its in the air, can you rotate the tires by hand and hear the clicking?

Maybe its something on your driveline or brake related, what about the rear locker engaging.

I had engage the four wheel d. Before I left the house when I heard clicking.bclicking disengaged it click like it always does.plus I can feel when it's in 4+4 .and I never locked up the rear..I don't understand how I drove back if my drive line isn't spinning wile in gear.and I went in and out of four wheel a few time to make sure it was clear.

 

Mybad but the four wheel disengaged like it always does.a slight click and I'm free.

 

My next move is to drop back drive line and open the diff up

 

Maybe I should Jack the front up-to see if it's still engaged.maybe that's how I got back home.but it felt clear and rear felt strong ...confusing as hell*!haha

 

Oh and i can hear the electric motor engaging and disengaging the fwd.sorry if I'm writing to much just want to give as much info.easier for process of elimination.ya know.thx guys

 

And yes I can rotate tire by hand and I hear it but not nearly as loud.I mean it was screaming when I took off out of driveway the first time I heard it.now it's sound like a baseball card hitting spokes.while in air.I think the weight has something to do with it
