Things are moving right along now... Next on my to-do list was putting the new tie rods together. I applied a bit of anti-seize compound to the threads of the tie-rod ends to make future adjustments a little easier. Once the tie rods were put together I installed them on the car.
A few photos of the nearly completed steering linkage...
Oops, I almost forgot to install the anti-sway bar! I don't know how I forgot about it until this point, I guess I got sidetracked by the steering stuff. The new 1 1/8" diameter bar that came with the suspension upgrade kit should be a big improvement over the relatively flimsy stock anti-sway bar.
One obstacle to installing the new anti-sway bar was getting all the excess POR-15 out of the bolt holes for the sway bar bushings. After two coats of POR-15 and a top coat of Chassis-black, quite a bit of paint was plugging up the bolt holes and nuts. However, some careful prodding with a utility knife and flat head screwdriver took care of the problem and the anti-sway bar was bolted to the frame in about twenty minutes.
Well, as it turns out I'm not going to be able to finish installing the sway bar right away. Without the weight of the vehicle compressing the front suspension the holes for the links that connect the sway bar ends to the lower control arms don't align very well. Rather than force them into place I'll add their installation to my "don't forget to do this later" list.
At this point the one major steering component left to be installed was the steering box and pitman arm assembly. Up to this point I've been procrastinating cleaning and painting the steering box since there's a pretty hefty layer of grease and grime caked on it. Once cleaned and painted the steering box will bolt to the frame and the pitman arm will connect to the stud on the power steering control valve (shown in the lower right of the photo below).
Well, I've been putting it off for long enough, time to clean up the steering box. For those who aren't familiar with it, the purpose of the steering box is to convert the rotational movement of the steering column into the left/right movement of the pitman arm. Here's a before photo of the steering box.
After a lot of cleaning, wire brushing, degreasing and a coat of primer I discovered a small problem. The oil seeping out of the steering box at the base of the wormshaft told me the thrust bearing seal was in need of replacement. Looks like I'll have to open up the steering box and check things out inside, who knows what's left for lubricant in there...
The first step in disassembly is the removal the lock ring. I didn't have a wrench nearly big enough so I used a hammer and socket to get things moving. Luckily removal of went pretty easily.
Next it's time to remove the thrust bearing adjuster.
Well, at least there's still a little bit of lubricant inside. Most of it had actually turned into a thick syrup-like sludge though. Should be fun to clean...
Next I removed the three bolts holding the side cover in place. Before removing them I took a second to break loose the lock-nut holding the adjusting screw in place. It's much easier to do so now while the cover is still securely bolted to the steering box housing.
Once the three bolts were off I removed the adjusting screw lock-nut and then turned the adjusting screw all the way down into the case.
Here the side cover and adjusting stud have been removed.
At this point I was able to easily remove the pitman arm shaft and worm gear assembly.
After a fair bit of cleaning and degreasing I ended up with the parts shown below. Apparently carburetor cleaner makes a good paint remover too!
Once things were cleaned up I took a few minutes to inspect each part for wear. Thankfully no significant wear was visible on the teeth of the worm gear assembly and pitman arm shaft.
In order to complete inspection of the worm gear assembly I removed the ball guide clamp and ball guides so that things could be completely taken apart and looked at.
With the guides removed (only one has been removed in the photo below) I carefully removed the steel balls being careful not to loose or drop any. There are 27 in each guide assembly.
Further inspection didn't reveal any problems so I'll clean everything up real well before starting reassembly.
To reassemble everything I centered the shaft and put as many steel balls into the assembly as possible.
The remaining balls that wouldn't fit in the worm gear were placed in the ball guides and packed with grease to keep them from falling out. Reassembly was pretty much the reverse of disassembly and went fairly quickly.
The last thing to check was the bearing races. No wear was visible.
So, it looks like I just need some new seals and grease in order to get the steering box put back together. Finishing this job is next on my agenda, with a little luck it won't take too long to track down the new seals.
