hi all
I am new to 4x4.
I got the 4x4 stuck and decided to engage the hub lock to no joy. the rear wheels still span and no drive to the front ones . I tried low range and high range to no joy.
THe 4x4 is a landcruiser lj78w 1992 model with button control hub lock on the dash.
can anbody help me whAT to check.
Stop the moving.
Engage hub lock button.
Move if you want to, and engage 4WD button.
You must be stopped and in Park or Neutral to shift into 4Low. The hub button must have the hubs locked.
The LJ78 Prado has electric hubs that are a common source of headaches... if they don't work, then probably someone without experience has serviced your front end and damaged the brushes.
We can supply adapters to install manual (read: reliable) hubs in place of the electrics.
Same happened to mine. Took 30 minutes to go down the hill thinking I was in 4x4, and six hours to get out using a combination of recovery techniques. It never reveals itself at a good time. I had the brushes, motors and slip rings replaced in the offending hub for around $100 with some good salvage parts and carry around a torx driver now so I can open them up and manually lock them if they ever fail again. I also had my axle seals replaced throughout to seal the moisture out. So far they have spent hours under water driving through the recent Manila floods and several other floods and river crossings before that and have worked flawlessly. Moisture is a problem in the tropics (duh!) so I still don't trust them. I'll carry the torx til they fail, and put manuals on when they are totally toasted. I am a bit of a sissy, so I like to push a button and engage and disengage the hubs when the road gets bad and it is pouring rain outside. Something about staying dry and just pressing a button makes me feel powerful...like man defeating nature or something. Though it is sort of like defeating nature in a game of Russian Roulette because you never know when they are going to fail... I would still gladly go to manual or permanently lock the electrics WHEN they fail again, not if.
