DIY: 370Z Lowering Spring Install

dmboye01

Thanks for the write up as well, made the job a breeze. I have been lurking on this forum for about two years now, decided to finally post.

This past week while I was getting my stock rays powder coated and I was already up on jack stands I decided to go ahead with the Swift swap.

Some words of advice fwiw:
-Borrow someones compressor (as large as possible) and impact wrench. I have a 30gal tank and 800ft lb impact and it still took about four tanks of air each to compress and de-compress each spring. I cant imagine doing this job without air tools. The passenger side lower strut bolt would have been almost impossible to remove with just hand tools. Possible, but not fun.
-If you don't know anyone with air tools just go buy them from a big box store, use them, then return them...Unethical, but an option.

I did the entire job over two days, maybe 1.5 hours the first day to get the struts and back springs off the car. Then 5 hours the second day to compress and swap the springs and then install back on the car. The second day would have probably gone faster had I not been waiting on air pressure for so long.

I threw in a pic of pre-20mm spacers and springs for reference.

Thanks again for the DIY! This is one of the most informative forums I've ever read.

So a couple days ago I saw a small puddle of oil under the driver' side of my car. I cleaned it up and waited another day. The next day there was only a tiny spot of oil. I've narrowed it down to the left strut as there's oil residue on the strut and transverse link. The seal must be broken.

Since I removed & installed the strut myself and took them to Nissan to have the springs swapped, I'm assuming Nissan is going to say I messed with it and it's not their fault. Really pissed right now. Especially since I only took it to them because I wanted it done right.

Update #1: Well, I managed to get them to warranty the shock. So, it looks like I'll get this corrected for free, which I did not expect. I'm consistently impressed with how well this dealership treats me.

Update #2: Nissan replaced my driver's side strut. I told them when I took it in that they should inspect the other side. Sure enough, it was leaking as well. So they're fixing that now for free. I just really hope this is the end of it.
