My 2006 l200 has always been a bit funny with 4wd - with the dashboard lights having a flashing center diff (never goes solid) when popped in 4wd. It always used to be the two front wheels were green. I'm not sure when it changed, but now the dashboard lights show the rear wheels solid green, with the front wheels not lit up, and when put in 4wd, the front lights and center diff light flash and never go solid.
What's going on? If it is stuck in rwd, will that be damaging at all? It actually feels a little sluggish, like the hind brakes are slightly on, especially noticeable when i'm accelerating.

Hi,

No expert but have had a similar issue.

The lights are flashing when in transition or at least 4wd commanded. It is recommended to not shift the 4wd whilst still in transition. Try driving at 5mph in a straight line or reverse to see if the diff lock goes solid amber as opposed to flashing.

If not, this could be a leak as the system may not have sufficient pressure build up. Check the vaccum lines to the diff for leaks, the hoses/lines go from inside the rear of drivers wheel arch (solenoids) down to the accumulator (about the size of drinks can) and then down to the front diff.

Also , look to find a rubber boot coming off the right hand side of the front diff when the car is selected into 4wd does the pin under the boot move freely, if not lube it up and slide it using pliers or screwdriver etc.

I can send pics if that helps.

All the best

2 rear wheels solid green is normal, as that is normal 2WD
This will not damage your truck.
4H can be used anytime anywhere as yours is an Aminal model it should have Super Select 4x4.
4L and 4Llc should only be used on loose ground mud snow grass etc.
If your 4x4 lever won't move there is a plastic bush that wears on the bottom of the lever.
