try taking the rubber boot of the 4wd stick it might be stopping the stick from engaging properly

I have made a 2 inch body lift a year ago and fitted a 2 inch extension to the normal stick, but never used the 4wd stick until last week when we had floods everywhere and a lot of mud and debris in the street to navigate. I will do what you said and see how it goes, but there is a strange clicking noise when I drive with the 4wd H as well, thanks

I have removed the rubber booth, and the 4WD gear shifts properly now, but there is still a clicking noise coming from the hub lock when driving !

dont drive on hard surfaces in 4wd. Clicking might be a cv but might also be a free wheel which need taking apart and lubricating

I only use 4wd on dirt or soil, the cvs are ok, guess I need to take the hubs apart and check them out, if there are some damages are there any parts I can replace ? thanks

Biggest issue is dry grease or rust.
