Installation
8. Check suspension members.
9. Insert spring strut and upper suspension, making sure that parts are correctly seated. Tighten lower of the two hex. nuts (5a), then tighten upper
counternut.
Note:In version 1 of spring struts (up to February 1970, production No. 080) the upper suspension carried a spacer sleeve (5n).
In version 2 (as of March 1970, production No.090) the spring strut carries a flange at top on threaded end for spacing rubber rings.
If during repairs spring strut of version 1 is exchanged for a spring Strut of version 2, use a new, lower disk, part No.116 326 00 67, for
upper suspension.
Instead of the two hex. nuts (5a) for upper suspension, a self-locking hex. nut together with a spring washer is used since February 1971.
