How to remove the steering rack from a 355

That's all for now. I expect I'll have the rack back in a week or two, and then will have to find a good weekend to put it back in. But hey, assembly is just the reverse of removal right?

Since I did this in my business partner's garage (I live in a condo), and my car is now occupying the space where his TR6 lives, I had to take his TR6 home to San Francisco for a few weeks. I had a great drive home.

 

Reference material.

Mitchell's post regarding rack removal can be found in the following thread (post#13). If anyone has other tips or related threads, feel free to post them here too.

Thanks for posting Mitchell! Very useful stuff. I would have only bought two copper washers for each bolt. I'll be sure to get a stack of them for installation. I'll also make sure my friend is around to help when it's time for the rack to go back in. I was guessing that aligning the rack-brackets would not be fun at all.

One data point: I was able to remove the rack as a one-man operation, but I can see where installation will certainly require two people!

I don't think I would have been brave enough to dig in, without you having led the way.

This really is a tough job. I wrench on motorcycles for a living, and still found this tedious and challenging. And my entire upper body hurts now, the day after.

 

$1,400 for R&R is a good deal for this much work!

Based on all of the good things I've heard, I'm planning to ship mine to Atlantic too.

 

Thanks for the heads up!

 

Thanks guys.

Just shipped mine off to Atlantic today.

Oh. One important thing I forgot to mention: It's a good idea to keep the AC lines sealed up or at least wrapped tightly in plastic wrap at the ends. Or you could even re-assemble the lines, to prepare the car for the wait, while the rack is touring the country via UPS. Apparently the oil used in AC systems loves to soak up water, aaaand the dryer component (just under $300 if you get the one in the yellow box) will lose it's ability to dry if it's left open. Just in case, I've ordered a new dryer. It's an aftermarket one. About $60 delivered. I'll post a link to it, once it's proven to be a good fit and to work well. It's from a company called Polar Bear Inc.

Now I need to track down some high-quality green o-rings of exactly the right size for the parts of the AC system that have been opened.

 

The rack is back. Good thing I have all next week off and no Christmas plans. I'm going to vacuum and charge the AC system myself too. (you can see the vacuum pump in the background of one of the photos).

I re-installed the rack today. My camera's battery was dead, so I just have a couple iPhone shots and some tips.

It turns out that the studs that hold the sway bar in place can be tilted and removed. I had put rags over them during the removal. Here's a photo of one being removed. Every bit of extra space you can get, helps.

To re-install the rack, insert it from below the car toward the passenger side. Once it's about as far to the right as it will go, the rack will clear the brake/clutch lines and can be slid into place on the driver's side.

Take two long zip ties, and insert one into the other and then poke them down through the empty grommets for the coolant/AC hoses.

Then go back under the car, and connect the other ends around the rack. Then cinch it up, until it's even with the mounting points. This will free up your hands for working the mounting brackets into place.

Not much to look at, but the zip tie is the white stripe around the rack. Obviously, this gets snipped once the rack is bolted into place.

It turns out that the mystery holes (the ones with rubber plugs in them in the corner of the trunk) have a purpose. When you're under the car you can stick your arms through them to reach the upper bolt for the steering rack mounting brackets.

In the second photo, you can just see my (long sleeved) right arm poking through the oblong hole in the corner of the trunk, and my (black gloved) finger poking back through and touching the bracket.

When bolting the power steering lines to the rack again, you must do the larger one first (19mm head). If you do the small one (17mm head) first, it's impossible to get a wrench on the larger one.

Start by attaching the larger hose under the car (this is the reference photo from when they were all connected, but it's the left-most hose at the top of the screen). Then feed the other end up toward the footwell. Attaching the large hose at the bottom will hold the hose in place while you connect the banjo bolt at the top.

Once the larger banjo bolt is fully tightened down (you won't get another chance, once the small hose is in place), you can install the smaller tube. This one is small enough to hold in place and slide the banjo bolt through, without attaching the lower end first. (though that would probably work too).

Once the power steering lines were all connected, I topped up the power steering fluid. Next I re-installed the heater hoses and topped up the coolant. Then I re-connected the air-conditioning lines, using new o-rings. AC systems use special "HNBR" o-rings. They tend to be green, but not all green o-rings are HNBR. Apparently this type of o-ring is resistant to the PAG oil in the AC system.

That's as far as I got today. In a few days, when I have time again, I'll use a vacuum pump to evacuate the AC system, and then re-charge it. Oh, and I'll install a new dryer. (since the AC system was open for a while, and it kills the desiccant.)

Of course, I'll properly sort out the coolant level and power steering level along the way.

 

Finally got it all back together. Including removal, re-installation, and all of the peripheral stuff, I spent four days wrenching (about 24 hours total), and about 15 more hours researching and ordering various parts and tools.

It could have been done in about half the time, but I tend to get caught up in trying to make things "perfect". You'd be amazed how much time I spend cleaning parts I hope to never see again.

The AC has been evacuated and re-charged. Power steering fluid, drained a second time, and re-filled. I flushed the cooling system with distilled water four times, and finally filled with 50/50 distilled water and Mercedes coolant.

Doing the alignment was easier than I thought. The workshop manual spec's out the measurements. A metric tape measure and a laser-level made quick work of it.

I drove about 40 freeway-miles home tonight, and then topped up the fluids. Feels great.

If I had to do it all over again, I'm not sure I would have gone DIY. I might feel better about my decision to go it alone once the soreness wears off.
