Hey guys question. For a while now the bottom half of my engine has just constantly been getting more and more covered in grease and gunk and just this stuff that is impossible to get off. I never new where it was coming from, thought maybe it was just road dirt, or coming from the oil pan. Cant believe I never realized this before but it has to be coming from my rack because my boots are HARDCORE f'ed up and ripped and barley on there anymore. I plan on replacing the rack real soon but I cant afford it right now. I am about to change my oil pan gasket, and clean all the **** up, just wondering if there is anything I can do temp. to keep it from getting dirty again before I change the rack.
 
Seeing that the seals are probably worn and leaking, you may want to replace the rack.

As stated, you will have to remove the tie rod ends. They can be removed with a tool that looks like a giant "pickle fork", it's less than $8,
or some stores will rent/loan one. Remove the cotter pin & nut on the tie end, stick the tool between the rod end and the arm it connects
and hammer away. The bigger the hammer, the easier it comes apart.

To change the tie rod ends, do them one at a time.

Loosen the tie rod end jam nut 1/4 turn, then unscrew the tie rod end from the rack. Turn the jam nut back 1/4 turn to return it to its
original position. With the tie rod end removed, use a machinist square to measure the distance between the end of the threaded rod
and the jam nut. Sit the bottom of the square against the end of the threaded rod, and the end of the blade of the square against the
jam nut.

Install the boots and use some good quality hose clamps to clamp the new boots in place.
Duplicate the jam nut measurement on the rack and then install the tie rod end and tighten the jam nut.

Reinstall the tie rod ends in the spindles and plan on having the front end alignment checked.



If you decide to replace the rack (best plan) here's the tech note...
The two inner tie rod ends are usually what wears out, and at $45 each, it's better to get a replacement rack assembly since they
are part of the package. The rack is about $100 + a $40 refundable core charge, which you get back when you return the old rack.
Be sure to ask for the GT or high performance rack, it has fewer turns lock to lock than the standard rack.

The flex coupling for the steering shaft needs to be disconnected before you can get the rack out. You should disassemble the
coupling by removing the 2 bolts that hold it together. The lower part of the coupling will then come out with the rack,
and can easily be removed.

The bigger the hammer, the easier it comes apart.

Remove the two bolts that bolt the rack assembly to the frame and then pull the rack down. Get a catch pan to dump the fluid in
when you disconnect the hydraulic lines. I replaced the rack mount bushings with some Energy Suspension urethane ones.
When you re-install the rack assembly, put the rear bushings in the rack assembly and lift it into place.
Then install the front bushings & washers and tighten down the nuts. Doing it this way makes room for the hydraulic lines
without having them bind against the frame.

To change the tie rod ends, do them one at a time. Loosen the jam nut 1/4 turn, then unscrew the tie rod end from the rack.
Turn the jam nut back 1/4 turn to return it to its original position. With the tie rod end removed, use a machinist square to
measure the distance between the end of the threaded rod and the jam nut. Sit the bottom of the square against the end
of the threaded rod, and the end of the blade of the square against the jam nut. Duplicate the measurement on the new rack
and then install the tie rod end and tighten the jam nut. Then do the other side: the front end will need aligning, but the
toe in will be close enough to the setting of the original rack to drive.

Buy several extra quarts of fluid to run through the system to flush it when you change the rack. The car needs to be up on
jackstands for the next step. Fill the pump up, start the car, and turn the wheels lock to lock to bleed the air out.
Then stop the engine, disconnect the low pressure hose (the one that is secured with a hose clamp) and drain the pump.
Re-connect, refill and do it several more times or until the fluid looks clear and not burnt or black.

Power steering pressure lines:
Each hose uses an O ring on each end to seal them. The hoses will swivel when they are installed and tightened into place.
That is why there are O rings on the fittings. The O ring is the part that actually makes the pressure seal. If you slide the nut
all the way back as far as it will go, you will see the O ring and the groove cut into the center section of the fitting.

Sometimes you will get some white Teflon rings with the pump or rack. The rings go on the threaded part of the fitting to
reduce or prevent small leaks. They are not meant to seal the pressure part of the line or substitute for the rubber O ring.
Heat the white Teflon seals in hot water and they will be easier to install. You can install the fittings without them and not
have any leaks if the O rings seal good.
 
Thanks Joe, always helpful, definitely will be coming back to this thread when I change the rack out. I guess I just wont do anything to it and I'll just have to change the rack sooner so it doesn't get dirty again. Dont want to remove the tie rods unless I am changing the whole thing.

Also I plan on going to a manual rack from a parts store with the adapter from flaming river. Anyone know which I should get, I know I can use a rack from 79-82 with manual steering, but when I looked at my computer at work I think its like 79-80 and 81-82 have different part numbers, I am guessing it is just the turn ratio? Anyone know which is better?
 
If you are going to use the car as a daily driver, leave the PS in unless you have clearance problems with the turbo.
That way you won't need arms like the incredible Hulk when driving in Orlando traffic. Top that off with no A/C and
the car won't be fun to drive in the summer heat.

I had a PS hose go out and had to drive home from downtown Orlando at 5:30 in stop and go traffic. It was very
tiring to steer the car when it wasn't rolling good. Parking it was a major arm wrestling effort.

Removing the PS will also necessitate a idler pulley in place of the PS pump and a different belt. You probably already
have that listed on your "parts to get" list.
 
Well I am still going to try it out and see if i can handle it. I am going to keep all my power steering stuff so I can just order new hoses and put it all back together if I need to. I plan on running a standard pump or the breeze automotive alternator bracket that moves it to the driver side and allows you to keep the stock pump, havent decided yet.

Hey Joe, any idea on which is the better manual rack? The older or newer one?
 
if you get a dedicated ps rack its not that bad at all on the street, i accually like it better at speed, you feel more in control of the car.

its not really a fair comparison to say a manual rack is like a faulty PS rack, i drove my car with a bad PS rack and it was a chore to turn the wheel at anything under 10 mph, the only time that the manual rack is a PIA is when im making a 3pt turn, and sometimes bakcing into parking spots
 
If it's temporary until a new rack is installed,you can buy split dust boots.They are made to be installed without taking any of the parts off.Just cut the old boot off,and slip the new one on with the fasteners.they were prety cheap as well.I got them at Autozone for my neighbor's old Ford.

I have no experience with manual racks, so I can't give you any advice in that area.
Hopefully someone else can chime in and give you some good input on which one is best.
 
K thanks Joe.

Vinnie thats what I was really looking for was a quick boot style that is split. I dont have them at my work for my rack, I'll have to call autozone today and see if they have any.
 
Man, I feel stupid. All this time, I was under the impression the boots on a steering rack actually helped to hold power steering fluid in the rack. :doh:

So, if you're seeing power steering fluid leaking from your rack boot(s), even if they're not cracked, then chances are there's a seal in the rack, itself, that's leaking and the fluid is just creeping on out through the inner tie rods and on out through the boots, right...? :scratch:

Ugh. If that's the case, then poop on it, teh Notch is getting a manual rack and I'm transplanting the good, non-leaky P/S pump from there into the Black Pearl... :notnice:

You are correct.

There is an O ring and a felt or teflon wiper at each end of the rack housing. The boots just keep the dirt and rocks off the shaft.
That helps the wiper and O ring last longer and protects the rack shaft from getting torn up by dirt and road debris.
 
You're welcome.

BUT....you really should just go ahead and replace the rack assembly and get an alignment.Mine was leaking,and I did every quick "fix" I could find,then I just bit the bullet and replaced it.Just like a new car afterwards.New rack,new outer tie rods,makes a huge difference.Especially if the rack on your car is original.It's really not that big of a job,and the rack you have,if it's leaking,means it's only going to get worse.

Replace the entire rack, just because of a couple of cracked dust boots? :scratch:

Well in my case I know I need a new rack beacuse of all the oil I am loosing. If you just notice a tear or hole in the dust boot I would replace the boot right away it if is an ongoing thing that gets worse and worse, you will eventually need to change the rack.

I just noticed at my work there is a part number for the racks but they are all discontinued. I guess a flaming rack it is.
