I only did the bearing swap because I was collecting the parts to make a nice double ujoint steering shaft without buying the flaming river shaft kit.
I could have used the stock shaft with little or no modding, but the stock shaft and the little tiny CV boot on the upper joint was shredded and icky.
Since I was going manual box I decided the little bearing and the double ujoints would make that 6.5 turns lock to lock a little smoother.
btw all I have to do is extend the shaft by 4" and re-clock it a few degrees to proper center the halves.
To intall the bearing only takes about 1 minute if you clean the grease off of the steering wheel shaft where it comes out of the fire wall to make the old bushing removal quick and easy (takes another minute or two.
hate to sound like an *** but its is true-er than true, you find a first gen astro/safari and simply take it off the end of the steering column where the steering shaft comes out.
tools you will need to get the bearing at the wrecking yard:
a 3/8ths ratchet with the 7/16" socket
7/16" wrench (just in case)
a hammer (just in case)
a couple flat blade screw drivers small and large.
1. take the steering box shaft upper off on the van so you can slide everthing off (use 7/16" to take out single bolt) and tap on the upper coupler (if needed with the hammer) to free it from its aged location. the shaft telescopes down so that you can pull it off.
2. use the small screwdriver to gently slide the "scratchy/grabby inverted star" retaining washer carefully to prevent breaking it or tweaking it beyond usability.
it might turn inside out but that is ok because it will still work in its new direction. be careful not to lose the little "wave" spring washer the it is holding up.
3. use the small screw driver to pull the big wire clip up and off
4. with a back and forth twisting motion pull off the little sheet metal cap
5. use the large screw driver to pull and pry the plastic bodied bearing retainer out of the tube and down the two inches of protruding shaft. if the shaft is dirty it will hang up a bit, if it is rusty it might hang up more.
now you have all of the parts in the picture on the right.
when you get home to put it on your car knowing what you do from pulling the parts off the van you will be a pro at putting the new parts on. very straight forward.
I recommend cleaning and hand packing the bearing with real grease (not just oil or WD-40) by hand through the narrow seam cracks (takes a few mins). To ensure a long and happy bearing life.
