this job is not too hard considering i did it and im only 15 1/2 years old
you will need a spring compressor in order to take the spring out
be sure to get one of good quality or else it may suddenly let go and cause injury. after you may need to get you camber adjusted and maybe the toe

have a good time

It's cake. Three top nuts and the 2 strut bolts. Remove the assembly and before you put the spring compressor on it, use the 17mm box end and a good crecent to bust the strut top nut loose. Unless you have access to an impact wrench, Then just hit it real quick. Might want to use a lot of liquid wrench through this whole process. I use a $10.99 spring compressor I bought from Harbor Freight. It comes with safety straps if you want to use them. No need to compress the spring much. Start cinching it down a bit and lightly push down on the spring til you know most of the pressure is off the top hat. Then remove the nut the rest of the way. Do one at a time so you can reference the reassmbly. I think the painted side of the spring goes on the outside?? Other'n that, ask more questions.

On the N13 Pulsar: The rear springs are so weak, you don't need a spring compressor, but I'd use one for the Sentra. You needn't worry about caster/camber/toe-in because it's all controlled by the inner ends of the links. Just swap 'em in and out. That's it!

Later, taters; Off to a better place. Catch me there!

yes the spring is part of the strut you must remove the assembly then remove the spring. And I agree with the kid who first responded use a good quality spring compressor cause I have seen springs let go its not pretty there is alot of stored energy in a compressed spring and it can kill or mame.

no no.. what im asking is can I take the strut and spring out as one whole unit.. since they are being replaced both? ( ie: do i have to take the spring out from the strut to take it all out )

You have to take them out as one whole unit; the spring is pretty much bolted to the strut. Basically, you don't have to worry about the spring, or spring compressors or anything at all, since you are replacing both spring and strut anyway (assuming you don't have to separate them to return them for the core charge).

The tricky part of this job is lining up the holes on the strut flange with the knuckle when reinstalling the strut/spring assembly. I had to use a floor jack to compress the strut a little, just to help the holes line up. The help of a friend is highly recommended to help muscle everything into place.

Good luck, and have fun.

Yes accually you do need to use a spring compressor and as I said in my first post you must take the strut (spring and shock assembly) out as a unit then you will need to take off the bearing or hat which ever you choose to call it and reinstall it to the new strut assembly. and even if you purchase a new hat you will need to compress the spring to install it safely. Have you referenced you factory service manual it will help in this greatly.

Yeah, sorry, I was just going through the removal process only, wasn't thinking about putting the new one in. My bad.

can I use a set of lowering springs with stock replacement struts? Or would say a set of the KYB GR2 struts work a lot better? Also if I lower the car ( 90 B-12) say 1" - 1 1/2" would 195/50/15's still clear with no problems? Thanks

If you use lowering springs with stock struts, they'll most likely not last. GR2's are typically used as OEM replacements as well. You should probably wait until you can get something decent and get good struts like AGX's and then get some good springs.

as for lowering, I have a 2" drop and no problems running the 195/50/15's. There seems to still be plenty of room under there.
