I took my less than 10,000m 07 Commander out for a drive in the (sandy) desert last weekend for the first time last weekend. I did not get far.
I was driving on sand tracks, probably less than 5 miles in Low Range when I got a loud knocking sound from under the drivers seat, I think. After lots of to'ing and fro'ing, having switched off LR and the anti-slip, a long (50metres) in reverse stopped the knocking. The next day I tried again, the same thing happened.
It is at the dealership, but I have no faith in them*, so would appreciate some thoughts to steer them in the right direction.
* They just fired four good people.
I seriously doubt that you you needed to use 4-Low. Ahmed is out in the desert all the time and very rarely has to use the low range. 4-Low is only for very difficult situations such as rock crawling, deep mud, and sand in some cases. You should NOT
go faster than 25 mph (40 km/hr) in 4-Low. Using your low range for for a distance of 5 miles is probably not good for the system.
Here are the 4-Low instructions from the Owner's Manual:
Four Wheel Drive Low Range — Low speed 4 wheel
drive. Locks the front and rear driveshafts together.
Forces the front and rear wheels to rotate at the same
speed. Additional traction and maximum pulling power
for loose, slippery road surfaces only. Do not exceed 25
mph (40 km/h).
4 HI to 4 LOW
With the vehicle at speeds of 0 to 3 mph (0 to 5 km/h),
key ON or engine running, shift the transmission into N
(Neutral), and raise the transfer case T-handle. “The 4WD
LOW Indicator Lamp” in the instrument cluster will
begin to flash and remain on solid when the shift is
complete. Release the T-handle.
