I have had Ford pickups since 1970 and probably 50,000 yearly---In 1974 had to change drag link at 7,000 miles---- in 2007 had to do ball joints on my 1999 with 350,000 miles- no problems with shocks or tires--however I have seen many on the road that needed some attention and most were probably owner induced or un/underqual repaired at some cheapass tire store

I believe the twin I beam is one of the best suspension systems on the planet, especially for lite/medium trucks---but believe that the move from k-pins to ball joints was a step off a cliff.
