Let me start out by saying I currently have my complete suspension sitting on my workbench to be reinstalled within the next two days, minus the control arms to be R&R (remove & replace) at a later date. Read my Race Pages post and you’ll understand.
The Monroe replacement strut that I am installing does not come with springs, not many do. I am sure you can probably find them, but I am unclear as to why you would want to replace them. The steel in these springs is about the toughest thing on these Toyota’s! Seriously the need to replace springs is rare unless they are broken, or your want to go with a different vehicle ride height, or you are stepping up to a high performance handling package.
It is not clear what you want to do, there is not much you can do to the springs to improve your ride, the ride damping comes from the shock/strut hydraulic or gas chamber depending on type. When the shock/strut’s resilience is gone you need to R&R the shock/strut. The spring supports the weight of the vehicle and the shock/strut regulates the bounce of the spring = smooth or stiff ride; depending on the rating of the shock/strut.
Interesting Info
The spring spacers were originally sold to compensate for tired springs on the heavier cars and trucks. When one spring was collapsed more then the rest you could insert one of these spacers into the tried spring as an attempt to even out the ride. I don’t know about the newer types but the originals had nothing to keep them in place, so every time you’d hit a hard bump they end up on the road. Every once in while I’ see one lying to side of the road. When they first came out they were laying everywhere, looked like a flipping cow pasture.
The only thing the top nut does is securer the shock/strut ram to the mounting plate. There is a specific torque value for that nut, do not exceed it. There is a bearing below that nut and you don’t want to screw it up or worse yet break off the top of your shock/ strut.
Probably more information then you needed, but hey’ I am cooking waffles this morning…. I am just finished my last one Now to get greasy
PS> Be sure to know what your doing with struts, they can tear you up, literally
