2000 toyota tundra 4.7l front axel fell out on passenger side. replaced ball joint , but noticed a metal ring on end of axel seemed a little bent. put everything back together tire has some wobble.

Probably broke the upper ball joint.
If nothing else is damaged the cost of the ball joint is around $25 in most areas plus labor.

sounds like cv joint

Without knowing where the noise is coming from, you won't have much luck fixing it. If it happens when you are moving you may have to get someone to stand next to the truck and listen.

1. Before servicing the vehicle, refer to the Precautions section.
   
2. Remove or disconnect the following:
   
   • Front wheel
     
   • Spindle nut
     
   • Wheel speed sensor, if equipped
     
   • Outer tie rod end
     
   • Stabilizer bar link
     
   • Lower ball joint
     
3. Press the stub shaft out of the hub.
   
4. Pry the inner joint out of the transaxle or intermediate shaft.
   

To install:

NOTE

Use new circlips, split pins and self-locking nuts for assembly.

1. Install the inner joint so that the circlip is felt to seat in the retaining groove.
   
2. Guide the stub shaft into the hub.
   
3. Install or connect the following:
   
   • Lower ball joint and torque the nut to 43-52 ft. lbs. (58-70 Nm)
     
   • Stabilizer bar link
     
   • Outer tie rod end and torque the nut to 17-25 ft. lbs. (23-34 Nm)
     
   • Wheel speed sensor, if equipped
     
   • Spindle nut and torque the nut to 144-187 ft. lbs. (195-253 Nm)
     
   • Front wheel
     
4. Check and/or adjust the wheel alignment.
   

likely the upper ball joint, but could also be the structure that holds the joint.

Lift the passenger side of vehicle. Remove tire/wheel assembly. Remove the axle nut. Remove the tie rod end nut. Smack the side of the housing the tie rod end goes into to pop the tie rod end loose and out. Remove the sway bar link. Remove the lower ball joint nut. Smack the housing the lower ball joint goes into to pop the ball joint loose. Pry the lower control arm down to pop the ball joint out. swivel the rotor and strut assembly to the side. Pop the axle out. Reassemble in the reverse order.

if u have u joints there should not any fluid near your bearing other than grease... if it is leaking anything other than that it is probably brake fluid... i would suggest checking your brake cylinder and brake line leading along side the passenger side

the problem with your truck is your knuckle bearings. I just replaced them on a friends truck and it sounds like the same problem. Just look on the inside of the front hub close to where the front axel attaches to the hub. If the seal is gone you will have a ring inside the hub on the axel shaft.

Call your Toyota dealer; they may be under a recall.
