I did a search first and didn't find anything related to binding in 2wd, hopefully I didn't overlook something...
I have a 2006 Toyota Tacoma SR5 V6 four door, completely stock with 61k. Last summer I would frequently experience what I would characterize as binding when doing slow speed turns in parking lots or navigating turns at intersections. Soon as the steering straightens binding disappears. This is not in 4wd, just 2wd. I try turning on 4HI and off again to make sure it was actually releasing. The binding went away when my snow tires were put on for the winter and returned when the summers were put back on (I think it's temp related, not tire related). This year the binding is not so severe but does it even when the steering wheel is straight. I get a slight shutter as I move away from a stop which then quickly disappears.
I took it to an independent shop today to diagnose. The mechanic immediately noticed the shutter upon driving it. All CV boots and U-joints were in working order, no leaks at all from differentials or transmission. We were also trying to assess if a front wheel bearing was bad, given road noise, but there was no play or noise through a straight-blade stethoscope.
Thoughts or ideas? Is it possible for CVJs to bind even when moving straight ahead? Thanks.
