TRD Pro, lifted and now driveline vibration

[fur_pig]

I put the toytec spacer lift on my TRD pro coilovers up front and the 2" rear springs they come with. The rear seems to have lifted more than 2" which is a common complaint here with those springs. I can deal with that but I now get a driveline vibration from 50mph on. It's very high frequency, not a tire/wheel issue. Has anyone had this and shimmed/spaced to bring the rear driveshaft angle back to stock?

The driveshaft angle wouldn't really be a problem with 2-3"- the 4runners have a sliding yoke on the driveshaft that takes up the very small change.

How was your alignment afterward?

Toe and camber spot on, caster in the front only 2 deg since i'm on stock UCAs.

Bumping this back up. It's driving me crazy, definite rear driveline vibe 40-80mph. Nobody else having this issue with lifts?

Go have your tires balanced.
