high mileage 94 front suspension

[tp85]

Hey guys,
I have a 1994 K2500 Suburban with 160,000 miles on the clock. It is a great vehicle, and my wife still loves it..so I gotta keep it rolling. It certainly has had it's share of problems over the years...mostly little electrical stuff and normal wear items. I just got done replacing the intake manifold gasket for the second time (first time was at 80K) and, of course, that egg-shell heater hose connection on the manifold. The drivetrain has been solid.

After 160K on the original hardware, I'm starting to get a little worried about the front suspension/steering. 160K just seems incredible to me...not needing to replace any front end parts (other than the idler arm/pitman arm). But I guess the 3/4 ton parts just can handle a lot more than 1/2 ton parts.

Currently, there is a faint click coming from the front end during tight turns over a bump and my lower ball joint boots have small splits. Given the miles, I'm thinking that a complete rebuild may be a good idea. I'm talking upper/lower ball joints, tie rods, upper/lower control arm bushings, sway bar rubber, etc. Am I crazy? I have seen that there are kits available (e.g. http://www.p-s-t.com/), but I have always used GM parts. So I'm not sure about the kits. How about the half shafts...I'm sure the CV boots are about to splits after turning all these miles. How about the differential output shaft seals? I sort of figure that, once I'm into the area, perhaps it would be wise to just do everything.

Any advice or comments would be greatly appreciated.
Tom
