I have no idea why this is so hard. I have a fair amount of experience working on car suspensions. But none with trucks. I'm putting on OEM 901 coils and OEM N98 shocks on the rear. I get the old shock off and start to compress the old spring then lower the axle. But i cannot get the damn spring out. The bumper piece inside gets in the way. Plus my spring compressor is a external one from Autozone and its so long its hard to position on the spring in the first place with out having something in the way. What am I missing? Tips? I'm almost ready to have someone do it for me.

 

No need for a spring compressor on the rear. Jack up the driver side rear. Remove the tire. Disconnect the sway bar end link. Let the axle droop. Pull the spring out. Put the new one in. Repeat other side. It should be that simple.

Now the shocks might be fun as sometimes you have to cut them out.

 

Be carefull of your brake line!
