I have a 2002 F150 4x4 SC and 6K miles ago I replaced the following:

-driver/passenger ball joints (Moog - uppers and lowers)
-Moog idler arms
-passenger wheel bearing (NAPA)

I have been greasing everything every 2K miles...I jacked the front end up today and noticed that I can grab the top and bottom of the passenger tire and it mover slightly...any ideas? Thanks.

 

up and down ..or ... side to side

 

I put one hand on the top and one hand on the bottom and could slightly tilt the tire in and out...tonight I noticed some whining/squeeling coming from the passenger side...could a wheel bearing let the wheel move like this? Thanks.

 

possibly check your lug nuts might be a dumb idea but its fast and simple

 

yeah...I checked the lugs nuts but it didn't help. The whine coming from the front passenger side makes me think wheel bearing...could it cause this problem? Thanks for the help.

 

is it a whine or more of a squeak?

 

I once put a new hub (wheel bearing) on a Grand Am that was bad out of the box. it let the wheel tilt down so much the caliper bracket dug into the rotor. That was a cheapy from Autozone though.

 

Its kind of a squeal that comes and goes...Im going out right now to disassemble the passenger side and figure out what is wrong!

 

What size tires are those and what is the backspacing on your rims? It looks good, I want my truck to look like that.

 

Thanks. The tires are 33x12.50 with 4"BS. Well it turned out to be the wheel bearing...put a new one on and all is well again...wish I hadn't lost my receipt, NAPA refused to replace it under warranty!
