Diff Lockers ... educate me...

(1/3) > >>

Big G:
Please tolerate a numpty but could one of you experienced lads put me right on this. I feel a bit daft asking but but here goes..

 Have had my Def.90 for about a year and love it for taking my dog over the fields (Mates farm) She brings me back stuff I shoot and,looks at me a bit old fashioned when nothing hits the ground (often).

Now I was surprised that I nearly got stuck the other day even with Diff lock in. I know how wet its been and I have got some biggish Mud terrain tyres on.

Question .... What if any is the difference when I hear people say "Fit Diff Lockers" to when I put the Defender into Difflock?

Thanks for your patience ...........  G

TDi90:
no worries mate we all started somewhere.
land rover was fitted with a standard centre diff lock (the one you engaged in this instance)
"diff lockers" are a very EXPENSIVE aftermarket thing that fits into the diffs, to lock the wheels in a forward motion.
they are for "hardcore" offroaders so to speak. probably not something you will need!

L90OOK:
The 90 has 3 diffs...one in the Transferbox & one in either axle.
The 90 comes with std fitment of a difflock in the transfer box (centre diff).  Locking this ensures the axle diffs turn at the same speed.  However you can still get stuck if one wheel on both axles loses traction.
Diff Lockers can be fitted in the front & rear axles (ARB are the favourite with many off roaders).  There are many different versions on the market.
By locking all 3 diffs the vehicle can move as long as there is traction to one or more wheels
Hope this helps  :afro:

extreme90:
in reality a 4x4 is only actually a 2wd, just is drive is transmitted to front and rear wheels

in normal drive ( no difflock ) drive is transmitted to all 4 wheels, but when offroad the wheel of least resistance will spin, which then means all drive is transmitted to that spinning wheel
by selecting center diff, drive it split 50/50 to front and rear axles, but again, the wheels of least resistance will spin, which then only gives you 2wd

if you fit locking diffs ( mine are ARB air lockers which i can manualy lock up as a choose ) you can then lock both wheels together on that axle
which combined with center diff gives you a true 4wd as all 4 wheels are locked together

sounds good, but when used road, they get you even further into the S***  :roll:

As said above they can do a great job of getting you more stuck. Also if your driving other say a grassy field where all the tyres generate equally poor traction then locking all the diffs will only be of limited help. They come in to there own on rougher ground or ground of varying conditions (one wheel on dry dirt and another in mud) were the tyres do not generate equal traction.
