I have a bad wheel hop at 65-70mph. I have checked all the linkage underneath my truck. I notice that both front shocks had fluid dripping down the sides. I replaced all four shocks hoping this would cure the problem. NOPE! I raised the left and right wheels and discovered that my left upper ball joint has movement. My truck has 45k, no off road driving or oversized tires. Why would the joints wear out so soon? And is there an after market joint that is stronger than the original?
