We'll the guy at schwabs made the call for new rims because where the other ones mount up to the Lugnuts seems to have been smashed in by the Lugnuts being put on to hard. So we went and put the front two on and went on a drive and it improved the vibration by 80%. Then we put on the rear 2 for a complete set of 4 and went on a drive. And it was back down to about 40% better.
We're ordering new tires to put on and see if it does this still. If it does i'm going to guess that the u joints are bad in the rear driveline. 10" wide wheels are very nice tho.
Tires will be here Thursday. In the. Meantime I could tried to put on new U joints and see if that eliminates it but should I wait for the new tires?
Is there any slop in the u-joints? Does your truck have the two piece rear drive shaft and if so, have you installed any spacers in the carrier bearing? I know the vibration didn't start with the lift, but it could be contributing to premature u-joint wear.
Yes I have the crew cab with the 2 piece drive line. I replaced the carrier bearing 2 weeks ago. And while I was at it I shimmed it 3/4 of an inch. ( I have 3" Lift and I read for every 1" lift to shim 3/4". ) this is the 2nd time I've replaced the carrier bearing in 3 years. But 1st time I've shimmed it. And I've never replaced the rear u joints since owning the truck.
Weird thing is with my smaller 315-75s the vibration seemed to be almost completely gone. And with the 385/70s it's there. So idk. I'm pretty stumped
Saw this and thought I'd throw in my two cents worth, but it sounds like you're close to a resolution.
I had new tires put on several years ago (not my current set) and at the first tire rotation, developed a pull and wobble when leaving the shop and driving through the parking lot. Drove right back to the shop entrance and explained what was happening. The shop rebalanced the wheels, installed them at the same locations, and the tech joined me on the test drive. Same thing happened with the tech in the passenger seat. Back to the shop entrance, "unrotated" (i.e., put the wheels back in the locations before this happened) the tires and NO MORE PULL OR WOBBLE. Determined it was a tire manufacturing issue. The shop replaced all four tires that same day.
Sometimes there is a "problem" during manufacturing that can't be seen. IDK what it is or what happens, but the one and only time I received some bad tires, the shop replaced them with no questions asked. This condition isn't brand specific. The tires I had the problem with were Goodyear. It's just something that happens sometimes. The tire manufacturers are aware this happens. They have been more than willing to replace the tires when it does happen.
