For A-Trac, you can turn it on at any speed, any time, I believe even in 2wd. The manual actually says to "Leave the system on during the ordinary driving so that it can operate when needed "I guess I misrepresented the question...do I have to stop to engage the A-trac or lockers? Or, can I be moving at a slow speed?
ATRACT is operated by a switch with uses anti lock brake system, so it can be turned on any time you are in low range. Diff lock can be engaged at low speed, consult owners manualI guess I misrepresented the question...do I have to stop to engage the A-trac or lockers? Or, can I be moving at a slow speed?
Your question about the rear locker (singular) and ATRAC has probably been answered, but it sounds like you probably don't have copies of the original Owner's Manual and the Maintenance Schedule. These may provide answers to questions that may come up over time as you gain seat time in your FJ.Going out wheeling for the 1st time into technical terrain, and want to know if I have to stop to turn on my rear lockers or A-trac. If not, what is the max speed and do I have to also be in 4L?
