1999 B4000 4x4
 

Hi
I am new to this forum and have a very good condition 1999 B4000 V6 4x4 and I am continually having problems with the 4x4 engaging the hubs.
I want to switch from the auto hubs and go to the manual hubs.
I am trying to find an aftermarket hub that will work on a 1999 model year.
Most suppliers I have found only start with this feature for models 2001 and onward
Has anyone replaced the vacuum hubs on a 1999 with manual hubs and if so who was the manufacturer
Thanks for your help
I love my truck and use the 4x4 feature often as it is used as truck for hunting & fishing.
Your help will be greatly appreciated.
I tried to search the forum but could not find an article on what I am after.
