My oem tie rod ends where still in great condition after 200k miles but I thought I would do some preventive maintenance and repair them. I thought I was doing a upgrade. Wrong. My old TRE where stiffer then this ones but I replaced them anyways. A year after installing the TTX'S it's time to replace my TRs before Firestone will do wheel alignment. Yes I now have to much play in my front end. Note to self if I got 200k out of a part that still was doing it's job correctly. Replace it with the same manufacturer. They didn't let me down after 200k it's a good sign their replacement will do the same.
