There's a tiny bit of slop in my '85 4x4 steering, attributed to slop inside the gear box. Is there a rebuild kit available for the gears/bushings inside that might be sloppy? I've never had one apart before so I'm not sure what's the problem inside. There isn't any other slop in my steering. It's not bad yet by any means, but it would be nice to tighten up a little. I have a replacement gearbox from a truck I parted out, but either way I'd want to sell a gear box with the rest of the power steering components on the vehicle I parted out.

I've seen rebuild kits online but they don't seem that descriptive and only seem to mention seals.

Thanks!
