Boss 302s Lower control arms (Updated Photo's)

[Tri-bar]

My set needs to be rebuilt. I pulled the bearings from the arms. Took measurement, found new Spherical Bearing at Summit Racing. Part# FKB-HIN12T Parts should be here tomorrow. Will let you know how it goes. If they fit the way I hope. Others with these arm can rebuild them.

@Tri-bar please post the procedure to rebuild, once you have completed.

Thanks for pioneering this!

Will do !
The Control arm end has a spring clip holding the bearing inside the bearing cup. Remove the spacers in the bearing.

With a small Left angle pick, slide it under the end of the spring clip.

Pry out the spring clip around the inside of the cup.

Remove the spring clip.

Remove the bearing, you might have to tap it out, It wont take much.

To install just slide the new bearing in, Tap the spring clip back in place, making sure the it sits in the grove that locks it in place. Put your spacers back in and there you go. Not to hard just a little time.

Awesome, looks simple!

Are the bearings the same for front and rear? I know there is an offset in the rear position for the arms--is this built into the arm via machining, or are the bearings different?

Bearings are all the same, arms are the same front to rear, the offset is in the spacers.

The bearings got here today and they were installed. They fit very well. Total time of rebuild about an hour from the time you jack the car up, remove the wheels and the control arms, rebuild the arms and put it all back together and drop it. As long as you order the bearings before hand. I only had to tap one bearing to get it to go in.
