2" lift. only one minor issue.

My 1st mod gone great . had a mate at a garage do most of the work as hes got the kit and lifts to get it done. so Shocks Springs and Rear shock relocation brackets all on and good.
Steering is fine. no pulling and it almsot straightens up without castor correction bushes. also has removed the wobble i had at about 45 mph

There is problem tho.
The four wheel drive doesnt operate properly, all i get is the flashing 4x4 light. there are no unusual noises or grinding.

Any ideas before i pick it back up and begin random diagnostics.

Sounds like a problem with the vac pipes so your front hubs wont engage.

Agree with Gaz mine did the same i just removed them an put manual lockers on did the same with my sportrak.

Yes mate I agree just check all the vacuum hose connections if you can see them.

well ive had a look under as soon as i in the garage negot to it. didnt try the 4x4 until i had it home. as my mate did the work. everything seems to be connected.
not looked into manual lockers.
idealy would want the vacum working again if that is the problem as its mainly on the road

Check the connections running down the inside of the drivers front radius arm.

I had a similar fault recently but to be honest it was the relays and not the pipes.

Just work through systematically
