Just completed an 1100mi trip from Charlotte NC to Fort Worth TX.
As the title says I'm having irregular wear. Alignment following the work and components installed was done earlier this year. Not much drive time on the alignment. Previous tire set was shot with irregular wear, I'll have to get back home first to tell you if its a similar wear pattern as described below.
Tires:
A used set of Toyo Open Country AT IIs. The two front tires are practically new with the hairs and casting mold edges left on them, rear two are more worn in at 4/32nds. Tires were inflated to 70 psi before the trip. 3-400lbs of payload in the bed with my tool box and two spare wheels. Tires were previously balanced, but I did not re-balance them before putting them on my truck.
Front end:
Spyntec locking hubs, EMF ball joints, new spicer U-joints, Synergy T link. Front end was greased before trip. Vehicle tracks straight. Shocks are a 1A Auto brand (cheap I know but it was better than the shocks that came on the truck when I drove it home). Of the front hubs the driver side was warmer, Text book installation on the locking hubs no play during installation. On the front axle the tires are cupping on the inner and outer edges. Center tread is more elevated, though I think its more from the cupping than over inflation for vehicle weight.
Rear end:
Rear hubs have been fully rebuilt and gone through using a Torque king 4x4 rebuild kit. Races, bearings and seals both sides. Text book installation no play or issues at time of installation. Both rear hubs had the same temperature (hand touch). Shocks are 1A auto. Weld on Reaper Tractions bars fabed to length for a CCSB Dodge 2500. Weld job was done by MB Diesel, not the best work to say the least, left side traction bar angled farther forward than the right side. Both rear tires are cupping on the inside edge.
Driving and my .02:
There is an irregular wheel vibration from both the front and rear more significant at 75mph+.
I'm hoping its something small and im over thinking it. I'm of the mind to drop my tire pressures to 60psi, the roads were pretty rough and my tires as hard as they were from pressure didn't help and neither did the cheap shocks. I'll get a wheel balance while I'm down here. Browsing online abit about rear solid axle tire wear I came across a few treads in forums mentioning 4x4 alignments. I'm considering getting one done before my truck leaves TX back to NC.
I haven't checked the hub play on the four corners yet, I'll do that before my trip back. I just don't suspect the hubs or bearings to be out of spec from the attention to detail I paid the assembly and rebuild process. But everything is on the table to question and consider at this point.
Thoughts suggestions advice?
