In a little bit of mud this weekend 4x4 was on and I pulled out on to the road going about 30( I say this because on another forum it says that it can cause problems) only drove for about a minute then pulled back off on to a dirt road and soon after I turned the steering wheel and it makes an very bad sounding click or crack. When the 4x4 is turned off it goes away and also only goes when I'm moving. Just dropped 2 grand into this truck on a leaking manifold new M/T tires and brakes. Also the shop said my u joints are bad so that might be the cause. I'm just curious to see what you guys think before taking it back in.
