Has Anyone run into this?
Been chasing vibration for a while. Had it as soon as I went to new tires and wheels, 305/70/16 on MT classics.
Blamed tires from day one.
On my third set of tires. Road force balance. Also centramatics. Screwed around with pretty much everything.
Out of desperation I jacked up the truck again last night running it in drive on jack stands. Was going to recheck my pinion angles.
Put it in drive to look listen, run it up to speed.
Driver's side rear wheel wobbles. I am like okay. Bent wheel, thinking road force balance was supposed to catch that.
So then I wonder how many are bent and start the process of rotating them out.
First I swap side to side on the rear, start truck up and run it. Driver's side still wobbles, Passenger side is fine. (should of had the bent rim on passenger side now)
Ok, so it is not a bent rim.
Digging deeper, Wheel bearing tight.
Pull tire back off check mounting surfaces all look great. Pulled brake drum, cleaned flange with wire brush, put wheel on without brake drum. (that was enough to ruin a couple lug nuts, studs are so long)
Start truck, wobble still there.
Being a full floating axle I was pretty sure it wasn't the axle, but I pulled it anyway. Axle appears to be true.
rolling the tire and hub without axle or brake drum still shows run out.
This truck has been a highway cruiser so I know there is no traumatic injury to the hub. 170k miles on truck. Maybe just a couple heavy tows.
So was it always there?
My factory alcoas had 285 tires and I never had a vibration problem. At least one that I felt I had to deal with.
So maybe it was always there and putting the wider and taller tires amplified it?
I ordered a new hub. Ouch. They are expensive.
I am still kicking around different theories. Things I can check tonight.
I cannot visualize any scenario where a bearing or race can cause this. Am I wrong?
Bearings are tight, show no wear or pitting. There is no bearing end play. So there would have to be a deformity in both the race and the bearing in order to cause this?
Or could it even cause it?
I am stuck on the idea it can't.
Bent stub/spindle would cause caster/camber issues not wobble.
Just wondering if I should put bearings in before I throw a $300 hub on it.
I searched the web and found nothing. So I figure it is so common it's like everyone already knows this but me, or I just get the weirdest shit happening to me.
Thoughts anyone?
You guys know everything.
