Hello All,

I did a search, and could not find a step by step procedure.

I think that it will also be very similiar for earlier models, but please check yours.

Firstly, I would like to thank the many various threads and posts by BB members that I used to study from.

Also, I would like to thank papajam, a Mentor in every sense of the word, who always takes my calls and walked me through this change.

Next, while I did take a lot of pictures during the change, there were a few steps that I did miss or thought of a better way of doing the step later. So if you see the same picture, once to take bolts out and later the same picture to put the bolts back in, you are seeing the same picture, but the step is correct.

Some of the non usual tools that you may or may not have but will need for this project:

24mm socket
22mm socket
24mm wrench
22mm wrench
27mm wrench
pickle fork
Lots of sandwich baggies to keep nuts, bolts washers and the like together
Sharpie to write on those baggies
And if your like me, I like to wear gloves, so lots of gloves.
Charged up camera

If I have missed something, please let me know and I will correct it.

I am not a mechanic, but like most of us that have Alfa's, am learning and hopefully, this will help someone take the job on.

Let's start!

Vin

PSA!!!

Below you will see that I placed the jackstands on wood pieces. Please note that the wood is screwed together and that it has been mentioned that this may not be the safest method to raise the car. That it might be possible that the wood blocks have a chance of slipping against each other should accidental sideways force be placed on the car. see post 129 of this thread.

Please work safely.

Raise car and put on jacks. No comments from the peanut gallery please, but this system makes me feel safe under the car for long periods of time, when there is a lot of pulling and pushing going on. :p

I used the threaded rod technique found here on the BB to lower the springs safely. I used 3/8" threaded rod, 9/16" nuts and shoulder bolt. I don't know who gave me the idea of the shoulder bolt, but it was on this BB, so thanks to that person. You will see where teh shoulder bolt comes in.

Replace bolt with threaded rod. Double nut the top with washer and use shoulder bolt and washer underneath. Thanks to GV27, "shoulder bolts" are properly called "coupling nuts" or "sleeve nuts". Or I've gotten them at Ace Hardware by describing them as "tall" hex nuts
Auto part Pipe Suspension Bumper Suspension part


The shoulder bolt, aka coupling nuts, sleeve nuts or tall hex nuts, comes in handy underneath to deal with the shape of the spring pan and also helps with removal and replacent of the pan. Makes it easier to grab with the wrench.

Back to the spring pan. Remove the last bolt from the spring pan.

I bought 2 ratcheting wrenches, 9/16" for this part. Well worth the $15. There is a lot of turing to get that pan down safely.

Slowly and evenly, lower down the spring pan using the shoulder bolts to safely remove the spring.

I decided not to remove the steering knuckle, calipers and disc's. It's up to you. So, I used a 9" rubber bungie to keep the assembly suspended and not put pressure on the flexible rubber brake line.

Speaking of brake lines, its a great time to inspect yours. Look what I found!:eek: So I replaced both the front and the rear flexible brake lines, but thats another thread.:p

Up to this point, the Driver and Passenger are the same steps, but to remove the upper wishbone from the body is a little different. Not much, but a little.

Driver side. Remove air hoses and upper half of air filter box.

For S4 owners that have Power Steering there are some hoses and lines that get in the way. We need to move the heat shield out of the way to get at that big bolt.

On the inside of the wheel well you will find the nut. I worked alone so I couldnt hold both the wrench and the socket at the same time so I used my favourite third arm, locking vice wrench to hold the nut while I loosend the bolt from the inside.

Once the nut is removed, you will not be able to remove the shield as the bolt is too long, but you can push the shield out of the way enough to get at the bolt and nut.

On Driver side, I used 22mm socket on the bolt and 24mm wrench on the bolt. Remove bolt.

Onto the Passenger side. As with most things on the passenger side, the bolt is buried under the intake manifold.

So, remove the hoses, wires and such related to the intake manifold and remove the manifold.

Now for this side, I used the 24mm socket on bolt and 22mm wrench on the bolt. It was easier for me. Remove the bolt and the upper wishbone.

All suspension parts are now removed. I did the rest of the dis assembly on the bench.

Remove end caps. I grabbed them with pliers, twisted them back and forth and upwards until they came off. This one was really stuck, so I used the pliers and my favourite hammer to pop it off.

Now all parts, suspension and steering are off, so if you are going to paint them, now is the time. I used my parts cleaner, AKA laundry tub to get as much of the grease and crud off as I could.

Oh boy, did the wife have a fit when she saw this!:D

Some extra scrubbing got the tub back to normal.:D

Replace new tie rods and re measure to match, centre to centre original measurement.
Tool accessory Clamp Machine tool


Using 19mm wrench, tighten the locking nut.

Follow the same procedure for the passenger side and centre tie rods. Passenger side should be 5mm shorter than the driver side.


Time to re assemble lower wishbone.

I had a local shop press out and press in the lower a arm castor bushings as well as replace the upper wishbone rubber bushing with a lower a arm castor bushing. If doing yourself or a shop make sure the green retaining spring faces inward.

The large washer demands some attention. You can see that one side of the washer is chamfered. The end of the dogbone also has a bevel. These two are designed to mate with each other.

Take the arm and move it around. The new castor has grease inside that needs to be disbursed around. At first it will be stiff, then it will ease up as the grease moves around.

Attach other arm in the same procedure.

You need to pay attention to the arms. Note that only one of the arms has this scallop. It goes on the rear of the assembly.

When assembling, make sure the scalloped arm goes on the same side as the shock long bolt. If you get this wrong, you will be taking them off again as the tie rod ends will hit them. Want to know how I know? ;)
