Issues with our Explorer that I sometimes see on other Explorer's from this generation is uneven tire wear. The tires in the front wear down from the inner part or (toe wear). It might be wearing down because the shocks are old and worn or the sway bar links are not connected anymore. Also I think the tie rods are bad because there is play in the steering wheel and it's not straight. Another thing is when I go over bumps, I can feel it clunk together or maybe that could be balljoints also that need to be replaced. The car tends to wallow most likely because it needs shocks. Are my theories and guesses about these problems right? If not, please correct me.
