PLEASE HELP !!!! MANY Problems !!!!

I have a 87 Chero Pioneer

270K Miles

I have a bad "Jerk" coming from mid to rear of truck when going up hills, and coming out of 4x4. What I mean by jerk, is a sudden shaking of the vehicle... untill i change gears... NOT MOTOR MOUNTS

I also have a "Click" in my Right Front Wheel Structure somewhere, that speeds up when the vehicle speeds up and slows down when the vehicle slows down, and doesn't happen when I idle. NOT CV JOINTS, or U-Joints...

ANY HELP WOULD BE GREAT... THANKS....

i dunno about the "jerk" but i recently found that one of the bolts that holds the brake caliper to the spindle was non-exsistant and was causing a click. it turned out that someone had used an impact wrench on the bolt and stripped the threads out of the spindle which now has to be replaced, so you might want to check that all you caliper bolts are still there

Not sure on the 'jerk' thing, but your "click", are your hubs completely disengaged? If the one side isn't you'll get the sound you hear.
