Suzuki: Suzuki Vitara Free Wheel Hubs, free wheeling hubs, auto hubs

Question
I have a 1993 Vitara Sport. I have heard about free wheeling hubs but I don't know if my car has got them, and how to switch them off and on. Also, my accelerator is very stiff and although my car sounds to have a lot of power I have to floor it to get it moving. Any ideas?

Answer
Most 4wd vehicles have one of three types of front hub arrangements.
GM and some other domestics have a device that allows the front differential to not drive the front wheels unless 4wd is engaged.
Other older vehicles have manual hubs which must be manually switched from free wheel to engaged by getting out of the vehicle at a stop and making the change.
Many have "auto" hubs which engage when the vehicle is driven a few feet with the transfer case in 4wd, and disengage when the vehicle is backed up five to fifteen feet with the transfer case in 2wd.
The throttle issue is something that a mechanic will have to be there to diagnose.
