Thread: No driving through the brakes on a D4?

High range because I'm not selecting low range to drive up a 50m driveway (manual cars are much easier on this driveway as the clutch provides better control). Ditto for the van although that's just habit low could be used.

But my point is that my D3 doesn't care that I LFB in these situations.

Yes eevo, it's an auto thing (unless you're drifting or racing on a track then LFB is a legit method of car control) !

Mick, if I were you I would definitely use low range when reversing the trailer up a steep driveway. Much better for the transmission and much easier to control.

Two different driveways - the really steep one is my parents (parking at the top of a slope behind their Honda which I can't see over my bonnet and don't want to hit as it wouldn't survive) and the van is parked in a garage that has a snaking narrow driveway that is somewhat sloped (enough that the van will push the disco fwd when reversing if not careful). I think I will do it in LR next time I park it just to see if that is enough to prevent the rolling forward.

Interestingly my holden can park the van without rolling forward but it sucks at it because if you touch the grass verge at all it results in nasty wheel spin (and also I can't go up the edge of the gutter !).

Yep Eevo, it's an auto thing. Let's you goose it (a little bit) over rocks or through gutters, without taking off down the other side, thus compressing suspension and bottoming out. I only do it when necessary, and only in low range.

I use low range to back my caravan up any sort of hill, including my 15m of drive. You actually have to brake to stop it moving backwards up the hill with the caravan in low range, not to stop it rolling forwards.


Also the same in my Patrol. No need to slip the clutch and much better control. No problems using low 4WD due to locking hubs left unlocked and obviously no issue at all in the D4 due to the centre diff.

Sorry for the newbie question, but won't you get wind up in the diffs if you're in low range on, I assume, a concrete driveway?

No - the centre-diff locking is "intelligently" controlled by the Terrain Response system.

Cheers,

Hi Kieren, you'll only get wind-up if you lock the centre diff on hard surfaces. As stated above, D3/4 have "smart" diff locks that won't lock unless there's some slippage. Us blokes in the more analogue type D1/2s have to physically lock the centre diff, because we know what we're doing :wasn't me:
