I bought a suburban that has differential lock. The original sticker calls it;
Locking Differential-rear axle
I'm wondering how this works (ie wheel slip, electronic lock) he only paid $252 extra. It doesn't have 4x4 in it so I'm wondering how well this works as I have some pretty steep grades I'd like to try it on -
15-20% with gravel. I've got an old GMC 4x4 that pulls myboats up this grade with ease and I'm wondering if differential lock will make a difference under these conditions and allow me to at least get the truck up the hill or what conditions the differential lock is intended for?Thanks in advance!!
