@gmartin1215 I picked up a set of spring compressors from harbor freight, I ended up using an angle grinder to shorten them because the posts were long and getting in the way, cutting it a bit short makes things easier.
My advise is to unbolt everything, put the jack under the pumpkin and while the tahoe weight is on the rear axle go attach your spring compressor hand tight and then rest the frame on jack stands while you lower the rear axle, the spring will stay compressed and will fall right out, let the jack squeeze the spring by jacking the pumpkin and just slap the spring compressors on it. Super easy
