I have a 1999 4 wheel drive Suburban I use to pull my boat. It has automatic hubs. I have to back up a steep paved driveway to park my 17 ft. bass boat.
4 whl high and 4 whl low puts too much strain on the 4 whl drive mechanism when turning on the pavement. I have been told I can install lock out hubs and a converter, that will allow me to engage the 4 whl drive and lock out the front wheels. It will then be low range and will allow me to put less strain on the transmission when backing . I am getting ready to repace that transmission for a second time. Does anyone have first hand knowledge of lock outs for this use?
