Changing Springs

That may help.
If you do intend to do the spring swap yourself, I would highly recommend pnuematic tools and a strap style spring compressor. You will HAVE to have pnuematic tools to remove the shock nut and you will wish you had them for the spring compressors. The strap style spring compressors will go quicker and be easier to get into the tight spring spaces than the standard metal "clamp" style. You can probably rent them from an auto parts store.
