    Default difflock on gravel roads?

    Hi Guys,
    what is the opinion on driving +- 100km on a bad gravel road with the centre difflock engaged on a defender td5?

    it makes a noticible improvement in handling, just dont want to break anything.

    i did try a search but could not come up with anything handy
    thanks

    I use 4WD (centre diff locked) on the Jeep on dirt roads - definitley better.
    on the Colt I found it made it tail happy...
    I think it's personal, but theres no problem with it being locked on a loose surface mechanically...

    just remember to unlock when you hit tar!!

    it is strongly recommended.
    the LR transfer case is designed for this purpose.

    And when it does not want to disengage, which sometimes happens after driving a long distance with CDL on, just reverse a few meters.

    Apoc, I think you have it slightly off here.

    The Colt (as with other 4x4 bakkies) do not have a Centre Diff ... thus no CDL. But VERY TRUE, rear DL on makes it (especially empty) very tail happy.

    I use both my Ranger and my Jeep XJ in 4x4 whenever it hit the gravel... always have and always will. It makes a huge difference when at speed - especially if you tow a trailer!

    On a standard dirt road i dont use difflock, what for. High range 4x4 engaged is good enough.
    Only use the locker to get me out of problems, and engaged long time in advance.

    I have travelled many thousand Kms on gravel roads in my TD5 in HR center diff locked without an issue.

    I have heard there is a speed limit of 80km/h IIRC but have never travelled above that speed on dirt anyway.

    Oppers - sorry, I mean I engage 4H which is effectively the same as CDL on a land rover...

    on the jeep with some weight at the back it definitley improves things on dirt... I find in bakkies the rear wheels tend to scuff and throw the back around more than in 2WD so I tend not to use it...

    Hi Stromtrooper

    your approach is the right one. LR Tdi's and Td5's have open front and rear diffs. So locking the CDL is the correct thing to do. It prevents the power to be sent to the rear axle only when it breaks out at the rear.

    So engaging CDL makes these vehicles safer. But for ultimate dirt road handling fit a Eaton True Trac up front.

    I recently bought a new Puma and was given a voucher to attend the LR Experience training. This past weekend I went to the one at GeroteK. It was great fun and although I have been fortunate enough to have done everything and have some experience already, the instructer (Christo) made a comment which I thought is quite appropriate to mention here again.

    He said......."You have paid for it so use it!"

    AFAIK there is no speedlimit for using CDL, ...but doing more than 80kmh on gravel roads is looking for trouble.

    you are so right. Even 80km/h on a corrugated gravel road can spell trouble when in a vehicle with live axles.

    I have so far only travelled in one very capable 4X4 where even 100km/h was no big issue and that was in my VW T3 Syncrobus. And if things got dicy you just had to floor it and it pulled itself straight again.

    But not in wet conditions!!!!!
