Probably don’t need to say this but don’t use the engine brake when on snow or ice I watched a guy at my last job do it he jacked knifed pushing his cab into the fence
he was a know it all driver and didn’t ask nor listen so had it coming
Yes,that i didnt say,but also,if Wheel spin they may search is way but if you use Diff-lock then Powered Wheels may spin outwards.so be caution with that.I used Difflock just twice on during Driving inb my Years.Only use it to pull off.
and remember.In emergency ABS not working Properly when braking gently,and Air-Brakes work not like Car Brakes.So avoid Pumping.And dont worry too much “Now”
But be very cautioning when it warms up or rains,as your Tyres press the Water out of the Snow and Ice is left behind under your Wheels
Did you hear the presenter on the BBC this morning saying that drivers of large vehicles were CHARGING up the road then jackniffing,then holding up stranded motorists,a Highways Agency guy rung in to defend us,to say the problems are loss of traction.
A local MP,tends to use big words to knock us down,in the past he has written to the paper,to say we are monster trucks,and an inconvenience to his constituents on his patch,ah bless his ignorance.We tend to see" trundling" when nimby`s write in to complain,and the good folks that objected to a new electric train depot being built on wasteground,that it would reduce their house prices by £10,000,ah oh,pass me the Kleenex for a good cry baby.They did not like the noise and the dust that it may have been,and do not like progress and job creation,the house price is top in the criteria.
Do you have to stop the truck to disengage the diff lock,don`t think you can switch it off while in motion after you have cleared the ice and snow situation on the road?
toby1234abc:
Some manuals say you can not turn while diff is locked,it may cause damage.
A diff lock will make the vehicle go straight ahead, that is the idea, although in slippery conditions it wont do any damage to the driveshafts or tyres
Unless the manual says you can dis/engage the difflock on the move, then only dis/engage when stationary. When it’s engaged steering will be affected slightly, it’ll want to go straight on, if it’s adversely affected then difflock shouldn’t be needed anyhow. Don’t use for longer than needed, replacing the claw can be expensive.
No diff lock, only the tractive (fastest rotating) wheel rotates. 1 wheel drive.
Diff locks, lock the wheels together on same axle, giving 2 wheel drive.
Cross/axle locks, locks the tractive (fastest rotating) wheels together on different drive axles, such as a 6x4, giving 2 wheel drive.
Cross locks and diff locks engaged, lock all axles and all wheels together, giving true 4 wheel drive, such as on a 6x4.

A lot of vehicles now use Traction Control rather than diff locks, it does the opposite thing by slowing the spinning wheel using the brakes. It may sometimes be called ASR.

Right I might get shot down for not knowing this, but if I don’t ask I will never know.
I have heard of diff lock, but how do I engage it and how do I turn it off■■?, is it just a switch on the dash??
Unit I drive is an 2009 merc actros 2544
It will be a switch on the dashboard showing an axle, it will be protected against accidental use by a locking tab, which you push downwards before engaging it. To turn it off, just move the switch back to its original position.
