Steering Stabilizer
Sorry for the late reply, didn't see the post until tonight.
Stock steering stabilizers don't last too long if you go off road any or have upgraded your tires. I haven't checked the one on my DMAX yet, but I suspect it will get replaced when I buy new rubber. I have a 1981 Toyota 4X4 pickup, and the stocker only lasted about 4 months. I replaced with a Rancho, that lasted for about 22 years, but when I upsized from TSL 34-9.00-15 SuperSwamper to 36-11.50-15 swampers the front end was vibrating to much for me to drive it and stay between the ditches. It turned out to be the Rancho steering stabilizer. After 22 years, it deserved retirement. I replaced it with a Rough Country that I had acquired years ago, but never had installed. The new steering stabilizer got everything back to normal. Well more or less: I need a little more lift to get the lugs out of the steering arm on hard left hand turns. As it is, it sure hurts the turning radius in the woods.
