First things first, I have a vibration that increases as speed increases and I need to track it down ASAP. Thinking out loud here, but I just made a lot of changes all at once, so here is what is new-
Upper heimed a-arms, uniballs
Lower a-arms, bushings, alignment cams
Coilovers
OEM tie rods
OEM lower ball joints
any and all hardware
front and rear diffs with 4.88s and ARBs
tires and wheels
front wheel bearings
I'm going rule my tires and wheels out. I drove about 100 miles on them before all the other changes and they were balanced great. They are balanced with 8 oz of beads and they obviously aren't going to fall out like a wheel weight could fall off.
Driveshafts should be good, they were good before the changes. In the past when I was trying to diagnose a ringing in the rear end, I rotated the driveshaft in 90 degree increments to see if I had hooked it up in a different position and put it out of balance. No position made any difference whatsoever at highway speed.
The vibration got slightly worse when I put it in 4hi at about 45 mph. I think it being worse in 4 wheel drive would indicate that it's definitely something in the front end.
The suspension feels smooth on the highway.
Wheel bearings? Could have been pressed in incorrectly, but I'd guess it would be hard to mess that up.
Wondering if my alignment is the culprit. It went straight to the alignment shop after I did all the work, was aligned, after the initial drive around the block they had to realign it because the coils had settled. I have driven the truck about 60 miles since, with the vibration at speed. I'd assume the coils have settled more.
Here are my alignment specs-
Camber -0.2
Caster +2.6 left and +3.6 right
Total toe +0.22
If any of you guys are familiar with "DJ", he designed the Hunter alignment machine and drives a first-gen Tundra. His recommended alignment specs for a first-gen Tundra are-
Camber +0.25
Caster +2.00
Total toe +0.08
