Alfa Romeo front suspension

Another problem.
Boots not really in good shape
and I think a bump stop is missing too.

Boots are supposed to prevent dust to enter
the tight space between the shiny rod
and the rubber seal in the shock absorber.



164.0 Note the location of spring end.
 Top and bottom


Parts bump stops there are some for Koni as well,
 even polyeurethane ones 


164.1    Sachs repair kit                                                          Shock core diameter 22 mm
                                                                                     164.2




Tools well there are many out there you need a good tool , these springs when compressed act ekcately like the springs in the pens you used to take apart in school on boring days , compress them and they might fly a considerabely distance...remember how easy they were to compress , their weight and the distance the flev.

164.3




You are going to need some really sturdy stuff this is the best I have ever had
164.4



For the top of the strut you need another tool a very loooong socket 22 mm open alloving you to stop the shiny rod to rotate this one sadly didnt work its way to big in outer diameter
164.5 top mount three bolts 13 mm                                                164.6 the not so right socket 

164,7 So if you are out there to buy tools max outer dia. would be : 33 mm
Top mount upside down inner diameter of  hole for shock nut shown


Damned Pain Arrrrrrgh.
164.8
 This one fits perfectly sadly it comes without the opening that allows you tho fix the shockrod from spinning hence plan B a mole grip at the highest akcessible point on the rod.

Top mount out of car to clearer illustrate
                                                                        Torque 66 - 82 Nm.                               164.9

Start at the top Top mount 13 mm ringspanner or long socket .
Torque 12 - 18 Nm.                                    164.10







Now the base of the strut is the original Boge , the Koni is insertet into that and fixed to it with a bolt at the bottom.
To loosen the bracket you once again need a breaker bar and a 17 mm  socket. WD 40 might come in handy too.....

Torque 40 - 49 Nm.                       164.11
 Thes came of surpricingly easy , now remove the top mount before you remove these bolts completely or you will find it difficult to support the weight of the strut AND loosen the three nuts.

164.12 leave them the strut assembly is heavy.
pull them out when your foot is out of the way.
Secure the strut in a wise bottom bracket facing right or left or whatever you prefer , there are many many asymmetrical parts and you need to realign them.

164.13

Be careful you might lose a hand or two. Church in Verona Italy




Put your spring compression tool on and squeeeeeeese.MAKE SHURE SEVERAL TIMES THAT THE HOOKS SPADES OR WHATEVER IS IN CONTACT WITH THE SPRING IS IN THE RIGHT PLACE . Here shown with the molegrip at the top of the shock rod.

 Contactpoints at the spring                                                                                                                                                                                                                           Compressing tool and molegrip
                                                                                                                                                        164.14




Remove parts top to bottum here closeup of the molegrip position on the shockabsorber core, it really doesent leave any marks.

164.15

note the two screwdrivers pointing at the groove and the corresponding thing
 at the green screwdriver.
Bump stop ready to be shortend

164.17

164.16

 Last part lover yellow bearing to the very left.




Whats left in the wise.            A compressible rod.Some force is needed !!

164.18                                                                                                                          164.19


That upon release returns 
164.20


Boot and bump stop , Spring has lowered the car a lot so the bump stop needs shortening.
Box knife lubricated with silicone spray does the job.
164.21                                                                                           164.22


Assemble boot and stop.
from below 
groove and notch
 apply silicon spray
164.23


 Bearing on

Boot and stop on silicon spray eases it a lot.

Grease between rod and rubber seal
silicone based grease
                                                            164.24                                                                          164.25


And then on the lower bearing.
Remember orientation
Screwdriver tip at the recess for the start of the spring strut body still in same orientation as during disassembly.
164.26                                                                              close up botttom plate and spring 164.27



align the upper plate and the top mount , the impression from the spring in the seal is clearly on the underside , this alignmentspot too.

164.28                                                     164.29



Well since plan A was the proper strut socket and it didnt fit Mole grip again in position above the bump stop , you have to depress the boot and the bump stop.

Im waiting for a new driveshaft hence the delay in putting it back on the car . Torque for the top mount 13 mm nuts : Lower Bracket bolts  :


Well you could end up needing a pair of theese
                                                                                                                               164.31

Front trailing arm , front bush,despite the use of powerflex it doesent look right , we need to give it a closer look its powersteering oil all ower the place .
Torque 29 - 32 Nm.
                                                                                                                                                     164.32

You might as well be prepared for a lot of time , pain and suffering again under you car
                                                                                                                                                      164.33

Trailing arms usally comes with the two inner OEM rubber bushes preinstalled , some even with the outer ball joint.
Here hub assembly and brakes onto the outer ball joint.
                                                                                                                                                     164.34


Do you really want polyeurethane bushes , well at least the rear bush is reasonable easy to replace. Start your drillbit your stanley knife ad your Dremel                                                        164.35

Clean the aluminum casing , this is NOT clean    164.36


Final touch grinding paper onto the dremel and you end up with this GREEESE      164.37
SQUEECE
Do not panic if the bush tilts on it way through the aluminum casing,just continue   164.38

The aluminum casing jumps up like this 
164.39


Continue ,steel tube in GREEESE 164.40


This powerflex is asymmetrical
