Checklist for Strut/Spring Install...
Some people said not to install it against the way they are recommended to be installed. I have heard about doing it the other way to gain camber back. Still debating. Saw a few threads with people having noise problems.

I had to very carefully use a set of vice grips with protectors on them as high up on the inner shaft as I could to prevent damage to the shaft, and in turn damaging the seal. I was able to break the nut loose, then it was spun by hand after. A strap wrench might also work without damaging it.
I planned on taking them off in one piece and reinstalling the new assemblies already done. However, I need the stock dust boots. Can't find any replacements....Ughh

I feel like I'm gonna have a huge problem with getting the 21mm nut off the top. Why can't a socket be used to get it off? Seems the whole assembly can come out without removing it? Excuse the ignorance, suspension is new to me..

My FRPP stuff came with replacement jounce bumpers and dust boots for the front. I also bought the jounce bumpers they offer for their kits and swapped those out with the ones on the struts in the box.
I bought the FRPP jounce bumpers, just need the boots. If I remove the whole assembly, that 21mm nut still needs to come off right?
Is this why people say an impact gun is best? Because the speed breaks the nut free by not having the shaft spin. Looks like I'm gonna have to borrow an electric one..

I installed my GT500 strut mounts with the arrows out. The alignment shop said my camber was within tolerance and just my "toe" needed to be adjusted. But I didn't try with the arrows pointed inward first so I have no idea if it helped or not.
I recommended the red loctite on the other thread because of several reasons.
1. Are suspension components something you want even having a chance at coming loose in the future?
2. Most of Ford suspension bolts and nuts are 1 use only or are metal locking nuts. Once that locking compound is penetrated they no longer lock the same. Me personally, I bought all new strut and shock bolts and nuts just in case. The red loctite was used to put the brake calipers back on. If you are going to re-use the bolts and nuts then do what you want but I would want the strongest threadlocker I could buy if it were me.
3. (This is a duplicate to #1 but I did this to illustrate my point) Do you REALLY want any chance of these things coming apart while driving down the road. I'm not a mechanic or suspension expert and I may have gone overboard with the RED Vs the BLUE loctite but I know that I did the best I could to keep anything bad from happening by using it.

If this keeps going, I'll make it a sticky in the suspension thread for future reference.

Rob - I didn't think that was you in another thread. I get your point, as I too am no expert, but guys here said no way.
I got people from all angles telling me be careful for this and that, this is dangerous, the nut is impossible etc. then I hear people saying its all a cake walk. I'm having doubts. especially with no guidelines/instructions to follow for a complete swap out. Ive read 2 writeups that differ quite a bit on how to do things. The front is really worrying me the most with this top nut and which step to do first.

Now, depending on which parts you use (I did all FRPP stuff), you may or may not need a strut spring compressor and you might not need to compress it much. With the FRPP 1" springs and their adjustable struts, I didn't need to compress it much at all to get enough clearance to put the top nut on. Once that is on, torque it down, then re-install in reverse.
The back shocks are a piece of cake, and the springs drop right in. You should have no trouble getting those in in under an hour.
In the end, it's not a tough mechanical job and there's nothing that's tricky to get at, just make sure you take your time. Do one side at a time so you can go back and reference the other side if you're not sure. Keep plenty of beer handy.
Here's TacoBill's spring install for the front, which is a good starting point and reference for all:

Thanks for that reply! That clears up a bit.
After you say to only loosen up the 21mm nut, what comes after? Lowering the arm down to have the pressure on on spring released? Then flyer the spring is out....
Also how imperative is it to get torque ratings very close? For example, if I need 129 ft/lbs and my Tq wrench only goes to 100. Is it cool to get it too about 100, then crank down on it a little more with a regular wrench? Or am I crazy? Lol

The top nut is a nylon locking nut. The very top of the shaft has a hex head. So you have to hold that with one wrench while tightening the top nut with another wrench. I didn't use a torque wrench on this since the torque wrench I had wouldn't have worked.

Good video but you don’t have to remove the brake caliper on either end to swap out.

Now I see what you guys are talking about with the dust boot. After watching that video it doesn't look hard at all to take the stockers apart and reuse the boot and bump stops.
Good stuff guys! Keep it coming!
