Device to Compress Hydro Comp Spring

Does anyone have a device to compress the hydro comp strut on a 108 or 111 rear axle? I have the replacement, and the CD manual shows a "Clamping Device" but the pictures are not clear as to design etc.

Any details would be helpful. If you have a device that worked, i'd pay to ship and return plus rental fee.

thanks in advance,

Not needed! But be careful & NOT let the right side go down too far too quickly.

Much easier with the right shock absorber loose at the lower mount.

The manual shows that removing the strut you don't have to compress it, but then why does it show the need to compress when installing?

Replaced the strut today, and yes, you can install without a compresser device. I jacked up the right rear and removed the old strut, then found out that the axle needed to be lower, so I unbolted the lower shock mount and also needed to uncouple the brake line where the rubber hose connects to the rigid line. Easy to do and then was able to jack up right rear higher to enable the bolts on the strut to line up. bolted it in then reassembled brake and shock after i lowered the car enough to line them back up. Result...fixed the sagging rear and camber problem. the old strut was completely shot, now the car sits level and when you accelerate, the rear end does not drop and rob power doing so, it stays level and moves forward! I also adjusted the transmission pressure rod attached to the throttle linkage, and found that it was not correct, it was too tight and was pushing the rod back about 1 inch or so, after I adjusted to correct condition, my shifting problem went away, that is it no longer has a slow and sloppy shift between all gears. now the shift is quick but smooth, what a difference!!

Good day for the old 4.5.

Thanks for everyone's advice on these issues.
