Transmission related death wobble / Vibration / Undrivable!

[DonYukon]

What about the trans mount itself? I had one go bad and it caused quite the vibration

That's a good one right there Don! so easy to miss too.

I ended up getting the Firestone Destination LE3's in 235/75/R15 warranty replaced with some GT Radial HWY Terrain's

Definitely solved that vibration issue but now it's exposed another, under braking it's shaking the whole front end, no pull to one side. I believe something is loose.

There is like a on and off small oscillation type vibration still, but I really think something in the suspension is loose and needs to be re-torqued.

I hope so at least, hell it's about a brand new damn truck. Any insight helps. Appreciate the comments before too.

I had 2 Moog idler arms bad/loose out of the box back to back. Check over all the steering linkage pieces. New doesn't always mean good.
