G'day,
I had a right laugh doing this job too.
I knew its a close call getting spring compressors that dont end up "bottoming out" so to speak before compressing the spring & thought I'd bought the right ones to do the job, based on the springs coil size etc.
The strut had other ideas. The ones i bought were good quality, but i just needed a bit more. I ended up borrowing a mates set & used those in conjunction with mine to do the job no worries.
As others have said, this can be a dangerous job if you dont approach it with caution but if done so, its not too bad.
Like others have said, lay the strut down away from you & anything you cherish in your garage/driveway if things go pear shaped.
Some people also strategically place a few shop towels around in case the thing turns into a missile !
I think those compressors linked in one of the previous posts look better for this type of short spring.
