I am interested in seeing what (if any) problems you folks have had with the steering boxes on these trucks. I will start by disclosing that in my business (ranching) my trucks have a tough life. Most of them never leave a dirt road and some stay in 4 wheel drive for months at a time. With that being said I am going through intermediate steering shafts and steering boxes left and right. I just had one replaced at 28,000 miles and when it was rebuilt, the comments on the ticket were it shows wear and tear consistent with about 250,000 miles on the odometer. Yes it has 28,000 miles. Why didnt I go to the dealer for this? I typically do but have had to fix so many poorly installed steering shafts and boxes after warranty work has been done that I have found its best for my time and money to fix it correctly within my own mechanics for this particular issue. This is some of the worst quality I have seen in a steering system in such a short time period and maybe its due to the way they are worked, I don't know. I have trucks that go 200K easily on some of the worst roads in the country and the only issue to address is the steering system and front end play. I am averaging (on my one tons) about 40K miles per intermediate shaft and and least a new box every 50K for OEM or 100K for a quality aftermarket. Is this the nature of the roads I travel or do the pavement dwellers have issues as well?
