So I'm building a shopping list for my upcoming front end overhaul on the 2011 F150 (currently 115k miles, excellent overall condition, goal is to surpass 200k before a new vehicle). I"m intrigued by these Mevotech "Tough Terrain ttx" parts line. Its marketed as an upgraded line on both RA and Napa but is it really? I am looking at tie rods, upper control arms and lower ball joints. The comparision is between Moog Problem Solvers, Motorcraft or the Mevotech TTX. Does anybody have some experience? The Mevotech stuff is in the same ballpark as Moog with the exception of the UCA's as I can only find those at Napa which doubles the cost there. MC, of course, is a few hundred bucks more from White Bear but with the cost of the TTX arms from NAPA it would make this comparable. For inner tie rods, outer tie rods, upper control arms and lower ball joints: In other words $550 for Motorcraft $360 for Moog (Problem Solvers line) $550 for Mevotech Tough Terrain I don't mind spending the extra money for quality but if Moog is still good stuff I don't mind saving it either. I do like parts that are greaseable but not at the expense of a decent boot seal- which I believe many of the Moog ball joints are much better sealed than in the past, can't speak for the rod ends though.
