I am getting ready to install new rear struts and was wondering is it easier to compress the springs while they are on the car or wait until they are out? Thanks

The spring / shock assembly must be removed as a unit then compressed. This is a very easy job.

Thanks, It's my first time changing out the rear struts.

You don't have rear struts

Front struts yes.

I'd invest in a Haynes manual, not the best but better than nothing.
