99 Tacoma 4x4 Gears

I have a vibration in the front end. Narrowed it down to Carrier bearings. There are some needle bearings and a bushing inside the Right side. I've have a question of what is Yukon Gears and does mine have them? Also does anyone know the part numbers for the Needle bearing and the bushing? Is there any updates to these parts that I should consider?

 

Yukon makes a variety of aftermarket gears, r&p, lockers, axles, etc.

Unless they were swapped out by a precious owner, then no, you do not have Yukon gears.

 

What are Yukon gears. Just heavier or Lots of differences? I saw a post when looking for needle bearings and bushings and they had them for Yukon gear carriers. I had no idea of what mine would be or if they would fit?

My frontend had a growling such like it was out of fluid. Checking I did find the seals were leaking on both side but worse on the passenger side. I used a pry bar and found a lot of slop on the passenger side. I was prying on the shoulder of the CV axle right next to the carrier on the passenger side. Since it was loose I figured the bearing. Now that I have that side apart the bearing do not appear to be bad. I'm wondering if the large bearing behind the seal and retainer clip could be bad? anyone have problems with that one? I read that most problems are from the needle bearing and the bushing. When looking for the needle bearing and bushing I just don't seem to find them. Any one might know where I can find them for a 99 Tacoma?
