Buick35 Posted March 20, 2021 Share Posted March 20, 2021 How do I service the rear shocks on my 35 40 series?Should the lever be all the way extended to add fluid or not? Thanks. Link to comment Share on other sites More sharing options...
pont35cpe Posted March 21, 2021 Share Posted March 21, 2021 Your `35 may be like my `36 rear shocks, they need to be removed, clamped in a vise to where you can move the arm up/down, install fluid, and work arm up/down to get the bubbles out. Try not to spill any fluid, because you need to check for any leak. If it leaks, they`ll be dry in no time, bad seals need to be replaced or most likely shocks need rebuilt.

Buick35 Posted March 21, 2021 Author Share Posted March 21, 2021 Thanks.How stiff should the arm be when working right? Like a modern shock? Just wondered. Link to comment Share on other sites More sharing options...
pont35cpe Posted March 21, 2021 Share Posted March 21, 2021 (edited) Once you work the arm up/down it will firm up as the fluid is pumped thru valve/passages pushing the air out, then when you change direction of the arm it should be firm immediately when changing up or down movement. You will have to top off the reservoir, once you work the air out. Also the link needs to have zero slop where it attaches to both the shock arm(rubber grommet) and the lower plate. Also the fill screw on the reservoir might be tough to get loose with a screw driver i had to use vise grips to get mine loose. Hope this helps.

Buick35 Posted March 21, 2021 Author Share Posted March 21, 2021 Thanks,I noticed that my lower rubber was missing and had a lot of play in it so when I replaced it I found that the link had some resistance in it but not much.I've got some hydraulic Jack oil that I think will work. 1 Link to comment Share on other sites More sharing options...

I tried the vise grips but no luck.Finally with B-p blaster and a punch I got the cap to move.Now I just have to paint it and put it back in.Thanks 1 Link to comment Share on other sites More sharing options...
Buick36-49 Posted May 6, 2021 Share Posted May 6, 2021 (edited) Hi All, Looking for new rear shock links for my 1936 Buick Special. The correct link broke and the not correct link (someone rigged it up) broke too. Here is picture of the only broken one I have? Any suggestions? I also cleaned up and install new fluid in my shocks plus painted them. They don't leak!
