Had a problem with the tires wearing on the inner edges. Got to looking - the front end was definitely lower than I thought it should be for a 4WD.
Being relatively cheap at the time - looked into spring spacers. By the time I added the spacers I thought would be needed to bring things back up - it was less expensive just to replace the front coils, plus didn't sacrifice any suspension travel.
Pretty easy DIY job - lift the front end up, letting the suspension drop, unbolt the single spring clip, and work the old spring out and the new spring in.
IIRC, got a spring compressor from the local auto parts shop. Free, although a fully-refundable deposit was required. Just be careful and appreciate the energy that the spring has when compressed - don't become a 'stupid people trick'. :-)
Took it to an alignment shop afterward to get things trued up - from where it was, it handled curves like it was on rails after.
