Removing struts for 2003 lexus ls430
Most of the autoparts stores have the spring compressor you'll need. Front & rear have a thru bolt on the bottom, then the strut is secured by one nut at the top into the strut mount which should have a few nuts you have to remove.
The dangerous part is the coil spring that has to be removed. It will shoot off of the strut if you remove the one large nut on the top of the threaded strut rod.
This could really hurt someone!!! The pressure on the spring must be removed, before removing that nut and that's done after the strut assy. is off of the car!
You need to remove it completely with the strut mount, leaving the spring installed. Then, following the safety instructions for using a coil spring compressor, you can remove the spring and transfer the reusable parts to the new strut and reinstall. Leave the spring compressed and just go from the one it's mounted on, to the new one and put it in the exact same position. Look at where the spring is before dissasembly on the old strut.
I suggest a manual, there are details, like making sure the spring is turned properly to fit as it did before removal. Removing pressure on the suspension to be able to savely remove the strut without it binding & such.
I've done a complete car myself in a few hours, but I have all of the tools. Sometimes it's difficult without a HD Impact wrench, to get these parts to break loose, especially the nut on top of the threaded strut rod. A pipe wrench can be used to hold the rod on the old part, since it won't be used again and that will secure the rod as you loosen the top nut.
Be careful, follow the instructions in your repair manual. If you don't have one and you're attempting this type of work, you may want to spend a few $$$ just to have illustrated instructions right there for every step. If you know your cars, have a decent set of mechanics tools and the special equipment required for this task, it's not a difficult job.
