Grand CherokeeJeep Brake Lock Differential (BLD) Explained

A recent blog post by a Chrysler engineer explains how Electronic Limited Slip Differentials (ELSDs) and Brand Lock Differentials (BLDs) work and the thought process that went into designing the system. Here's a snippet:

Just to get this out of the way; from the Jeep perspective, BLD is not a substitute for locking differentials. It is a means to greatly expand the off road capability of vehicles that were not purchased with or do not offer locking differentials.

It's a great read for someone trying to figure out exactly how all the different 4-wheel drive systems work. Check it out.

 Re: Jeep Brake Lock Differential (BLD) Explained
Sounds like a pretty good system to me. The technique of using your brakes to help tranfer torque back to the wheels on the ground has been used for years with open and LSD (trac-lok) diffs. With the BLD system only the wheel in the air would get the brakes applied making it much more effective!
