When I got my'94 Ls I found both front springs were broken.
I replaced them myself,cannot remember how much 'cos I bought new front rotors at the same time.
You can do this job with any one who has removed a front suspension leg
before,say a macpherson strut.
The complete leg is easily removed and then you can carefully hold it in a vice
[i put some old lead flashing in the jaws so it was'nt damaged] while you remove/
replace the broken spring,
What you ABSOLUTELY MUST DO is get the most substantial spring compressors
you can get.[hire]?
I use two on each spring, these are strong springs, but are easy to control with
good compressors.
When the leg is in the vice,check before dismantling and reassembling how the spring sits in place.
Don't try to rush the job,make sure the spring is captured securely before
removing the end.
Looks scary but BIG BUTCH COMPRESSORS are the key!!
