Just purchased a rear end from a gentleman with the H9B axle code. The H9 obviously refers to the limited slip 3.55 rear end but what does the B stand for? Does it have a limited slip up front too? The google does not seem to give me any consistent answers.

And then if it does have a limited slip up front, is it worth having? I rarely use 4WD. Truck is a pavement princess except for the occasional trip up the pass into the snow. Really I'm only interested in it because the price is so low.

Thanks in advance.

 

Yes the B in the axle code suggests the front axle also had a limited slip diff, it's not that desirable for a street truck.

 

Thank you!
