Should you find yourself in a situation where you have one rear tire with no traction (ice, mud, off the ground) all the power will go to THAT tire. This will still be the case in 4wd, but your front wheels may help to unstuck you. The locking rear will bind together both rear wheels, and when you have one wheel with no traction, power will still be going to BOTH wheels. The limited slip works the same way, but is not AS effective.Let me ask, what good is a locking rear differential? I meanm, the truck already has 4WD. As I said earlier, I had a limited slip rear diff on my Ford Ranger and never knew if it did anything, but maybe it did.
As I recall, the locking rear diff has a button to activate it on the dash. So, adding it afterwards would be difficult. What about changing over to a limited slip?
Just curious. Obviously, the other equipment can be added (i.e. suspension and skid plates). I won't miss the AC outlet in the back, although it would be nice. The only other thing I kind of wish was different about my truck is a manual transmission. But the warden doesn't drive stick and on long trips it would be nice to let her drive for a bit while I play with the radio equipment I'm going to install (Yaesu FT-100 and FT-8900 amateur radio).
Unfortunately, all of that will have to take a back seat for a couple of weeks. This morning some dork turned left right in front of me and I plowed right into him. Smashed up the whole front end. It looks all cosmetic, fortunately. He didn't get off so lucky...the right front suspension on his Trailblazer is all messed up. The whole thing is pushed inward at the top so that the wheel is at a 45 degree angle, not to mention his fender and door are messed up. His had to be towed, I could at least drive mine away although the driver side front tire rubs when making turns.
There are lots of options for locking differentials... ARB makes an air-locker set up, Eaton make an electronic activated model... I'm sure there are others. Cost is in the $800 ball park. They aren't difficult to install, but you need a little bit of smarts to get the proper lash adjustments.Okay, but here's the big question...is any of this something that can be added aftermarket? Or am I pretty much out of luck on that?
Heck, the truck might already have it on there for all I know...I don't remember all the items that were installed and I didn't keep the list sheet.
