Whenever I turn corners or park etc at low speed forwards or in reverse I hear a nasty clunk in the rear of the car along with a slight shaking. The car is newly imported and had a few worn parts that were replaced. Would I be right in assuming that the nismo 2 way lsd would be to blame for this? If so how much am I looking at to replace it.

heheh I am sure there would be plenty of people will to swap it for free to a standard one :)

Mechanical diffs are a pain to live with, unless you take it out on the track, sell it to someone for $500 +they pay to swap it out :P

I can learn to live with it if that is how it's meant to behave :P. I've never owned a RWD car before let alone one with an LSD so i'm not really sure what to expect :). Are you saying that these LSDs always clunk at low speed?

yep absolutely.

The 2 rear wheels will pretty much always move at the same speed. So when you are doing slow turns like a carpark, the outside wheel is travelling much further than the inside wheel, so the inside wheel starts slipping/skipping to catch up, so it makes the naty clunking noise.

On the other hand, if you are doing track days or drifting and can put up with the noise day to day, stick with it. Tight diffs make an amazing difference to handling on the track.

The factory LSDs aren't very tight so they won't make any noise.

      Did tie rods. Steering now not "springing" back.

      Yep, there's a very minor drift left that happens a few seconds after letting go of the steering wheel, but not enough to bother me. Enjoying the car still!

      Steps to DIY sanding car back ready for respray....

      Sounds good.  I don't 100% understand what your getting at here. When you say, "I keep seeing YouTube videos where people have new paint and primer land on the old clearcoat that isn't even dulled down" do you mean this - there is a panel with factory paint, without any prep work, they paint the entire panel with primer, then colour then clear?  If that's what you mean, sure it will "stick" for a year, 2 years, maybe 3 years? Who knows. But at some stage it will flake off and when it does it's going to come off in huge chunks and look horrific.  Of course read your technical data sheet for your paint, but generally speaking, you can apply primer to a scuffed/prepped clear coat. Generally speaking, I wouldn't do this. I would scuff/prep the clear and then lay colour then clear. Adding the primer to these steps just adds cost and time. It will stick to the clear coat provided it has been appropriately scuffed/prepped first.  When you say, "but the new paint is landing on the old clearcoat" I am imagining someone not masking up the car and just letting overspray go wherever it wants. Surely this isn't what you mean?  So I'll assume the following scenario - there is a small scratch. The person manages to somehow fill the scratch and now has a perfectly flat surface. They then spray colour and clear over this small masked off section of the car. Is this what you mean? If this is the case, yes the new paint will eventually flake off in X number of years time.  The easy solution is to scuff/prep all of the paint that hasn't been masked off in the repair area then lay the paint.  So you want to prep the surface, lay primer, then lay filler, then lay primer, then colour, then clear?  Life seems so much simpler if you prep, fill, primer, colour then clear.  There are very few reasons to go to bare metal. Chasing rust is a good example of why you'd go to bare metal.  A simple dent, there is no way in hell I'm going to bare metal for that repair. I've got enough on my plate without creating extra work for myself lol.
