Unfortunately, in order to get the new rack back in I had to remove the inner tie-rod and bellows, just as I did to get the old one out. Also, the assembly came with the other hydraulic lines integral to the rack already installed. I'd removed these lines from the old one, which made it easier to get out. Plus, I didn't much care what happened to the old one, since I was replacing it. But since the new one had these lines on it, and I didn't want to mess it up, I ended up taking a couple more parts off the car -- the power steering return hose (which I had previously just disconnected from the cooler and pushed out of the way) and one of the brackets that retains the starter cable. After that, the new rack went in pretty easily.
Since I had to take off the non-reusable clamp that held on the bellows, I just used a couple cable ties to secure it back on. The inner tie rod I just tried to torque back on to about the same as I felt it took to get it off.
Oh, heh, and I almost had the thing completely back together before I remembered to reconnect the steering column! So I had to remove the rack mounting bolts again, but fortunately that was it. Otherwise, getting everything back together was a lot easier than taking it apart. Stretching the teflon seals was weird. I was sure they would break, but of course they didn't. The best way I found to do it was to pull them down over a needle-nose pliers.
Oh, and one other thing I almost forgot!!! There was an obscure instruction for installing the new rack that said that if the system was equipped with a check valve, it needed to be transferred over from the old part. I didn't know what they were talking about, so figured my system didn't have it, until I started trying to figure out how all the seals were supposed to go on (which I decided was not like the original ones were installed...). Anyway, I was staring into the inlet port of the old rack, when it struck me that there was a funny thing down in there. After a few minutes, it finally "clicked" -- the valve! Boy, was I glad that I hadn't either returned the rack yet (which I was planning to do at the same time I got the new one, since there is a $130 core charge) or put the hoses on yet, which would have meant that I would need to buy a new seal kit!!! The valve and a little retainer ring came out without too much effort. I used a pair of skinny needle-nose pliers. The retainer I mostly turned out sort of like a screw. For the valve, I kind of pushed open the valve a little and tried to carefully grab the edge without messing it up too much. Of course, by this time the new rack was already on the car, so I had to install them without seeing exactly what I was doing, but I think it went OK.
I flushed the system (almost according to the directions.....) and did my best to bleed it. I'm not at all sure I got all the air out, since after turning the wheel back and forth about a million times it still made a gurgling sound. But when I cranked the engine up, it seemed to work OK, and no leaks!!
But all is not over -- I took it for a test drive, and the steering pulsates a lot when turning. Mostly when going slowly, but I guess that's when the most assist is required. So, I'm guessing either a) there's still air in the system; or b) I need a new pump, since the old one might have been run too long with low fluid. Any ideas there, anyone?
