07 Tacoma making noises when driving from rear end

I have a 2007 Tacoma with 46,000 miles on it and has a pro comp 6 inch lift and 35's the left was put on about 8,000 miles ago. So the truck makes a clicking noise when I make right terns. That started happing about 3,000 miles ago and now the rear end is starting to leak oil supper slowly. Is the clicking noise a bad barring so that made the seal go bad?
If it's gon bad why so would it go bad with only 46,000 miles on the truck?
If thats the problem would putting 4:56 gears in it help it from happing agen?
With any help would be good
Thanks soo much!!!!

 

A clicking noise sounds like a bad bearing? Did the noise start before you noticed a seal leaking? Check your fluid level in your rearend and make sure its topped off before you continue driving it, could cause further damage if its too low. You will probalbly want a tech to look at this asap.

 

Sounds like one of the spider gears in the diff has a chip out of it.

Where is the oil leaking from? It's somewhat common for the wheel seals to leak on the rearends in this truck. If that's where it's coming from it's probably just a seal, not a bad wheel bearing. Those make a roaring noise that increases with speed in a straight line or turning.

Have you checked the oil level? If it's low, that could have damaged the diff for sure. Or maybe you will get lucky and just have to top it off.

Putting 4.56s in it probably won't help the spider gears if that's what's wrong with it. But it should take the load off the rest of the drivetrain.

 

k so today I pulled it all apart and the clicking noise was the drum brake so i fixed that do think it had any thing to do with the seal breaking. the only other thing that could have made it go bad is when I excerate and it shifts from 1st to 2nd it vibrates. So how would I stop the vibrateing coming from the rear end if thats the problem?
thanks for your help!
