Any Ranger owners out there who can tell me what this electronic diff lock is. It always appears on the spec lists for these vehicles but none of the Ford salespersons I've spoken to can tell me exactly what it is. Is it a true diff lock, do all models have it etc? Any help appreciated.

"Electronic differential lock, or EDS (german acronym for same), is not a differential lock as per usual. It uses the ABS sensors at driven wheels (i.e. left/right front on FWD, left/right front and left/right rear on quattro), to determine if one of the two wheels is spinning faster than the other. At some speed differential (approximately 25 mph / 40 km/h), the highly sophisticated fifth-generation ABS/EBV actually pulsates the brake momentarily at the spinning wheel, effectively transferring the torque through the open differential to the wheel with more traction. This system is effective, but due to the stress that it would create on the braking system, it is only used up to speeds of about 25 mph / 40km/h.
You should really hear/feel it work on front-drive models, as it makes the typical ABS type pulsating sound when activated during wheelspin. "

That is the best explanation I have had/heard.

I have that system on my Ford Escape, and never understood how it realy worked, never the less it works efficiently on the escape, and you can get all 4 grunting if needed.

Cheers
