I have a Peugeot 504 1975 GL saloon and i am ordering parts off Der Franzose to rebuild my front end steering and suspension. Im having trouble figuring out which upper suspension strut bearing fits my car.
Can anyone help?

image 1 is the only 504 upper strut bearing franzose sell but is only suitable for 1976 onward and mine is a 1975. The other image is an older 404 bearing.

Not really, im driving it every day and didn't really want to take it apart until i had the parts to rebuild it.
 
I could check with what I have but not for a few days.
Actually you probably won't need a new one, I never have. The rubber top is what gives trouble.
 
Hey wow....looks like you've got single circuit brakes. I thought double circuit came out before 1975. Maybe they changed during that year ?

I hope you keep the master cylinder upgraded / re-sleeved / get a new one every few years. When a single circuit master cylinder fails, you've got no brakes at all. It's sudden.
Not trying to scare you....just something to keep in mind. And single circuit ones are cheap to re-sleeve.

If you ever feel a change like you should pump the pedal (like in old cars where they used to suck air into the rear wheel cylinders on drum brakes). STOP CAR AND DON'T DRIVE till you change master. I had a really scary experience once and that was the early warning sign. You should never have to pump up disc brakes ....the hydraulic situation is quite different from rear wheel drums.

Funny you say that about single master. Best feeling brake pedal over the 2pot master. But 505 is better than single.
Dads 504 v8 seen multiple track days at sandown & Phillip island and runs single no issue. As well as our old 504 rally car did 17years competitive with no issue. Big job to change if you don’t have the skills or a donor car to take off.

As per the original post. As what graham said is right. What’s it doing for you wanting to change them? The standard ones are the best Sasic ones are rubbish.
 
Unless the original bearing is cactus from rust etc...There is a rubber seal that protects the bearing and I believe it is no longer available so be careful with this when you pull the strut apart. Clean the existing bearing with brake clean and blow out gently with compressed air. My 504 is 1972 and the bearing is still original as per picture below

505 brakes work much better, bigger booster and also better calipers with the same discs.

Are we talking about the same thing ? A single circuit brake master cylinder on a 504 ? It's held on to the booster by two small nuts and has a single brake line going into it. A three minute job.
Perhaps you are thinking of the booster ? Still only four nuts in the drivers footwell and a circlip holding the push rod onto the brake pedal.

Single circuit brakes are fine...all I am saying is that you have to keep an eye on the age of them, as failure can be catastrophic.

Big job to change the whole system to suit.
 
Oh, right.
I'm not really "with it" at the moment...too much stuff happening in my life and feeling dopey from Winter's hibernation reflex.
 
i did the struts on my 404 a while back and gave those bearings a good clean and a grease ,was amased at the difference in the steering
 
^ Interesting....glad to hear it did. If someone previously asked me I wouldn't have thought it would, even though that old grease gets very stiff with age. And I guess that even with a seal, dust will invariably make its way in.
