Locking Diffs - Air or Electric??

[Big Gags]

We went to Harrops in Preston to get it fitted, reasoning that if anyone knew how to fit one properly it would be them. Have no complaints. Very reassuring when travelling alone in remote country & allows slow & steady rather than bash & crash.

Thanks Cuppa - funnily enough I drove past Harrops today on the off chance that they were open on a Saturday (they weren't). If you don't mind sharing, how long did it take to fit and how much did it cost?? Also, do you know what their warranty period is?

Thanks to all for comments regarding the transfer case - the main thing I wanted to know was if the drive was always supplied to front and axles when in 4WD. So I guess that this means that when in 4WD and with a front locker engaged then you are always going to have drive to both front wheels and at least one of the back wheels.

I haven't had any experience with LSD diffs before - are there any "tricks" to using them when tackling difficult terrain?
