I have about 1000 miles on the LX470 since swapping out the dead engine. I have been getting more confident in it but the issues are starting to crop up, this one most concerning. I did some searching and didn't see anything matching exactly, but here is what I have. When the vehicle is cold, or only driven around town there is no symptom. If I get on the freeway and drive 60-65 for about 15 minutes, the front end will develop a wheel-speed vibration or shake only when under throttle. It's almost like a death wobble on a solid axle rig. If I turn left it shows up, and it will also show up if the suspension unloads, like going through a dip.
When I replaced the engine, I put in a new rack, tie rod ends, and then had lowe ball joints done plus an alignment. I Can't detect any play in the wheel. I am thinking since its at wheel speed (if I am going 15-20 and lightly accelerate the steering wheel will pitch back and forth, particularly on a rutted road). I am leaning wheel bearing, but if I make a hard left turn at full lock and give it some gas I can hear a slight clicking like a CV. What say the group?
