Bad Trunion bearings?

[Xander77]

With my wheel off the ground i have a little movement when pulling on the top and bottom but not side to side. I pulled the outer wheel bearing, inspected, and reassembled, the same movement was still there. Would this indicate the trunion bearings are bad or lose?

I was going to do a full knuckle rebuild this winter while doing a SOA conversion. My question is if it is the trunion bearing would it be safe to use it for the summer (not a daily driver) and just keep an eye on it if it gets worse?
Is there any thing else i can test to make sure whats causing the movement.

Thanks for any input.

Get a second pair of eyes and wiggle the knuckle for them. Have them put a finger up against the knuckle wiper retainer and knuckle ball. If they can feel the knuckle housing move, rebuild it now.

More likely you just have worn out wheel bearings/ races.

OK i did the test you suggested and there is movement between the wiper retainer and the ball. What does that tell us?
it's the same on both wheels.
its a 4/77 40.
30 spline and factory disk brakes

It tells you that the bearing wear is significant enough to warrant a rebuild sooner than later.

Yes i figured that from what Mark said "If they can feel the knuckle housing move, rebuild it now." I guess what I'm asking is what parts, or bearings .... are the problem. Obvious i will replace them all but i am just trying to learn more about diagnosing the problem to help others and myself in the future. Is it just the wheel bearing inner and outer or the trunion bearings or all of them?

Thanks,

Trunion bearing/races top and bottom of steering knuckle need to be replaced.


Post up pictures of your bearings so people can see what they look like.
