Any part of the suspension that is worn will usually place undue stress on other parts. Worn guide rod mounts will give abnormal tire wear but the main factor is diminished control when braking. Which is one of those things that, in a severe situation, might be critical. It's your call, I'm just pointing out the apparent risks.

The guide rod mounts aren't that bad, especially since you aren't dealing with the rust issues that WHunter faces in Michigan.

Place the front end on ramps (which provides weight on the front wheels). I used a come-along to hold the suspension in place, front to rear, which helps in reinstallation of the bearing bracket bolts. Measure the threaded portion of the guide rod mounts to maintain your alignment. Unbolt the bearing bracket and remove the guide rod mounts.
