I finally finished changing all of the seals located on the front suspension. I had to go to a friend's shop and use larger hydraulic press to take the suspension apart.

I finally installed most of the front suspension. I will attach the sway bar, steering links, bleed front brakes and adjust steering next week. The photo was taken just before installing the suspension.

I bleed the brakes and filled the suspension and steering box with oil and two of the oil seals leaked. The leaks were on the passenger side and cannot figure out why they leaked. I am going to use 140W gear oil instead of the recommended 90W gear oil. The driver's side did not leak and am glad because the steering box feeds the suspension. I had to make some custom tools to remove some suspension arms and working on this suspension is much more difficult than any Alfa suspension.

I put 85-140W gear and Lucas stop leak on both sides of the suspension and have one very small leak on the driver's side. I still have a large leak on the passenger side and have to see why it leaks.

I changed the rear pinion seal and it was very easy. The differential pinion nut is a 30 mm hex nut.

I am going to change front and rear engine gaskets next and hope to be finished with this car.

I also helped the owner to rebuild the two carburetors. The carburetor bodies are used on VW and on 356 Porsche but, the internal parts are all different.

This is the first BMW that I have every worked on and was lucky enough to find parts from Germany. I know that some Alfa parts are expensive but, parts for this car are very expensive.

I worked on the brakes and believe that there is air in the system. There appears to be a valve to balance the front and rear brakes and might contain some air inside.

I have restored a number of Alfa Romeo Giulietta cars and like working on interesting cars in retirement. I have met a number of car collectors and most of them have great stories about their cars. I few of them have Alfas but, most of them collect anything but Alfas. I think Alfa owners are a special type of person "eccentric" and I only driven Alfas since obtaining a driver's license in 1968.
