2004 GX470 with 140k, 2.5" OME lift and 33" tires.
Yesterday I swapped in new front rotors and brake pads (Napa rotors and Toyota pads). Took it for a ~30 minute pad bed-in drive followed by a few errands. Car felt great and the new rotors/pads definitely fixed my subtle brake shudder.
This morning on my drive to work I started feeling the "rumble strip" shudder at 20-25 mph. Fortunately my commute is super short so I parked it and took a look. Nothing visibly wrong. Thinking it might be something in the VSC / electronic system I disconnected the battery for the morning. Rumble vibration was still there during the drive home.
Observations:
Shudder starts around 15-20 mph. Haven't driven it faster than 25.
No steering wheel shake, no pulling to a side.
No shudder in park or neutral, even with engine revving.
No strange smells.
Still shudders coasting in neutral.
Transfer case seemed a little reluctant to shift between H and L
Is it time to flush the transmission? I crawled under the car during lunch and nothing seemed loose, wobbly or visibly broken. What are some other things I can check while the cars on jack stands? Thanks!
