I've made a post about the reliability at the 15 year mark of my 4R. This month marks year 16 with my beloved 4R. Bought it new. Fun driving in the snow in Central Texas in 4WD. Most of the work that has been done has been maintenance. I have replaced the front wheel bearings, timing chain cover leak sealed, TPMS sensors(5) replaced, new suspension, other stuff that I have done have been mods to make the ride more enjoyable.
What suspension did you put on it? I like that it looks just slightly taller than stock.
