diff locks ????
hi all
Sorry to appear as thick as a bowl of porridge but i`m still quite new to 4x4ing and was just wondering just what the difflocks actually do :oops: :oops: and what sort of damage could i do to my G if i don`t use them properly :?:
Also i was thinking of getting some new tyres as the winter weather draws in, any suggestions as to what would good in the cold weather.
cheers all

Hi Mahoney.
These sites may be of interest,, http://www.difflock.com/offroad/4x4explained.shtml,, & http://www.4x4abc.com/
Both sites have plenty off good reading..

Ha, ha, ha.
The site is named "Difflock",
The appropiate section is titled "Differential Locking",
and guess what? it does not even mention the only truck to have fitted diff locks in all its lifespan, the G-Wagen. It does not even explain the way a fully lockable diff works!
What a load of bull$hit
:lol: Yeah i know,, but barring their complete lack of knowledge of the G, it's a good site for lots of general info on off roading.
As long as I properly understood your question, heres an answer,
All a difflock does is lock the differential, the differential being that mechanism housed in that lump somewhere near the middle the axles, the differential being there in order to allow the wheel at one end of the axle to rotate slower or faster than the wheel at the other end of the same axle, this "differential" in wheel rotation being necessary to allow the vehicle to turn. Perhaps simpler to consider in another way, a tracked vehicle a skid steer loader, a zero turn mower or some remote controlled toys are steered by dint of braking one side/wheel or track relative to the other hence causing said vehicle to slew,towards the braked side obviousley.
Anyway a good demo would be if one pulled in to a grass verge at the side of the road, in a normal vehicle without diff locks the inner wheel will spin on the grass whilst the wheel with the grip will not rotate as in normal circumstances the diff simply allows one wheel to rotate relative to the other. With a diff lock engaged both wheels will rotate at same speed but the vehicle will want to move forward ( or back ) in a straight line only --- except that the wheel with traction will move the vehicle forward and the steering input ( especially with a 4WD ) will generally be sufficient to pull the vehicle in the desired direction, but the steering will not have as much effect as it would normally have,with 4WD and a difflock on the front even more traction but less steering.
Best bet is to take vehicle to a grass field at this time of year and experiment, you notice the difference in your vehicles behavouir/handeling ,best of all is a field with a bit of a slope and observe effects when attempting to move off uphill from a standstill etc. should not do any harm if revs kept in moderation , wet grass will allow sufficent slippage to prevent any harm to transmission.
The difflocks engage themselves after being activated, this will take a few meters to occur , then difflock lights come on.
BUT --- BUT --- BUT --- ENSURE ALL DIFFLOCKS OFF / DEACTIVATED BEFORE LEAVING "FIELD" or other off road area OR IMMEDIATELY YOU ARE BACK ON THE "HARD" or PUBLIC ROAD AS VEHICLE HANDELING WILL BE ADVERSLEY AFFECTED, OH AND you will knacker some part of the transmission or drivetrain and it will be "VERY EXPENSIVE"
Good luck,
Marcus
Had to take a breather there,
Did my previous make any sense to anyone else?
Did I realise how long it was going to take me ?
Have I nothing better to do with my life ?
Yes 3 dogs, 2 children and a wife.
So I have to go & face the strife.

Hi Marcus

many thanks mate.

Heres another link :D http://www.houseofthud.com/differentials.htm#locking%20diff
Better then the difflock explanation,, :lol:
i think my brain has just melted :shock: :shock:
to much info for one sitting better site though.

using diff locks and getting winter tyres with an address in london? where you going then aly pally ice rink off-roading
:lol: no just being prepared,
a good friend of mine said we a going to have one of the coldest winters on record this winter,if his right i will bye him a drink :wink: if his wrong he can pay for bloody tyres :twisted:
anyway going up to scotland soon and you nver know..................................
IF you are coming up to Scotland, it has started snowing here! The gritters are out, with snow ploughs attached and the snow blowers have been put in position!!
I have heard that this is going to be the hardest winter since 1949 There was 4" of snow on the Cairngorms at the end of September, that is the eariest on record 8) 8) :shock:

Aye, an the rowan berries ur hingin heavy. Coos ur birlin roon wi bums pointin' North. It's gonae be cauld :shock:
If the wee "coos ur birlin roon" how can their bums be pointing North -- except intermittently and transitently ( if there is such a wurd )
Perplexed,
Marcus
Jist birl an stoap :wink: Ave heard o' yon transthinguiy coos, ye git thum sooth o' the border. Jist plain MAD awf thur heeds. :shock: :lol:
It's only their een that ur birlin an that's cos o' the cauld.! It's bloody cauld auriddy -2 an it's only tea time ye ken :roll:
The gless isnae lookin gid eether! A'l hae tae look oot ma simmit a doot :!:
Ah so the tyres would seem to be good idea.
so back to the origina please guys :roll:
can anyone recommend any good tyres for this sort of weather.
opinions and experiences would be greatly appreciated.
cheers

B F Goodrich All Terrain seem like a good allrounder.
Would appear to be capable on road and most off road conditions.
Colin
cheers colin
do you have something similar yourself :?:
Yes that's exactly what I have, I was talking to someone else who has two G's and does a lot of offroad eventing, he reckoned they were good all rounders and very capable off road.
Depends what you want, you will get more road noise from these kind of tyres.
Colin
Thanks once again colin your a diamond.
right thats me done for tonight i`m going home to walk the bloody dog, grumble,moan wish i never bought the bloody thing ect,ect....................
I like BFG's as well. Even the MT's last well on road (no doubt more noisy and inferior road handling/grip, so may not be what you want in London!).
Slightly off topic but just fitted BFG's to my car. Not expensive and WAAY better than the Pirelli P6000's that came off it (they would tram line horribly plus poor wet grip).
If you don't want to spend loads try Colway Tyres. They do copies of BFG for not much money.

I have BFG Mud Terrains on both my Gs.
On the 463 Cabrio I have 33x10.5x15s. No rubbing during steering, but I am in the process of giving the truck a 1.5" spring lift to give a little more clearance in the wheelhousings.
On the 460 LWB I have 32x11.5x15s. At first they rubbed the inner wheelhousing at full steering lock, but a few taps with a half-jack in the right place and they don't rub at all now. Tread clearance at full articulation is no problem, as the 460 doesn't have the plastic wheelhousing liners that the 463 has.
As for noise, yes there is a little more than the stock tires - not an appreciable amount when I first mounted them, but a little more now. Never enough to make me turn the volume up on the radio. The trick with the Mud Terrains, as with any aggressive tires, is to rotate them frequently - about every 5000 miles or so. Also extends their life, of course.
Handling hasn't suffered at all. It's not like it was a sports car to begin with. :wink:
Handling off road is stellar.

yippee anyone for a trip to scotland

Sounds like a good idea Ian :wink: Mind an bring ma door :twisted:
do diff locks only engage in 4ws low?
cheers simon
:D Good Question ,
you should only lock the difflocks when in low range crossing terrain where you could get cross axled , or very loose slippy surfaces i.e snow , mud .
you could lock them in 4x4 high ( I now wait other opinions ) if the surface is loose enough .
the lights on the dash only come on when the diff is locked i.e some slip on the road, same when thay come off the light only goes off when thay disengage .
What does Scc28 stand for ?
Regards
Cliff
Where did the 4 wheel steer come in ?
No Simon, one can engage difflocks in either high or low, you may be mixing diff lock engagment up with 4 WD selection, ie. if in Low 4 WD is automatically engaged, whilst in the 460/461 models normally run in 2Wd only unless 4 WD is selected.
Marcus
Agree diff lock can be lock at any time but always under 5 MPH
