Front or rear wheels?
The rear knuckles have plastic bushings that I’ve already had to replace. The bearings shouldn’t have play in them at your mileage, heck I’ve only got 2500 more miles and mine are tight.
Make sure the hub nut is tight?
Is the play a loose tie rod? Loose rack and pinion gear mesh? Loose a-arm bolts? Maybe it’s the upper or lower ball joints?
I noticed because I installed arched front arms and noticed during final checkdown of all bolts, etc.
Play is hub/bearings. Bushings are all new and tight. Tie rod end tight. Ball joints new and tight. All verified. To confirm it was the hub or bearings, first I always check side to side movement in the tire to feel for tie rod end, rack, etc. No play there. Next, I placed my pinky between the outer axle cup and the knuckle where the axle goes into the knuckle while someone else grabbed the top and bottom of the tire and pulled back and forth. When the tire is moved top to bottom, I can feel the cup pinch my finger against the knuckle slightly. This ruled out ball joints, etc. as the entire knuckle would move if it were that, not just the axle cup.
Drivers side tight at 110 lbs. Passenger side I have retorqued twice, and it reduced the play to almost being non-existent, but it's still there. Then, my concern became over-torquing.
@JTW
Alas, the question of should there be any tolerance at all?
Sounds like the answer is no... Makes me wander what's up? Bearings were like new when I had everything apart.
@ToddACimer , regarding the axle o-ring, neither axle had an o ring on them. Axle nut threads, shoulder, splined back to 90 degree shoulder where it looks like the hub would seat, then convex shoulder where the bearing shoulder would seat. Definitely no o-ring on either axle as I always clean off the factory grease and re-grease before reinstalling hub onto axle splines.
I am OCD about my stuff, everything gets put out on shop cloths, cleaned, regreased (i.e. axle splines, inside hub).... Both bearings were full of grease from the factory also, and the retaining ring on the outboard side of the hub was covered in grease as well on both sides when I pulled everything apart.
Wander if they got rid of the o-ring for 2018 like they did the lower ball joint circlip per the parts fisce.
