How to tell if mount plate for struts are worn?

I've been looking around to see what the parts would cost for fixing
my suspension ails. The bumps are hard on my butt, much harder than a
few years ago. It's like the springs are sagging so I'm bottoming out
or maybe the struts are failing. It rides okay and handles in the
turns okay but the bumps are jarring my fillings loose.

I found http://www.mileaautogroup.com/ for one online store (there are
loads of them but seem to be front ends to the same few catalogs) but
I don't know yet if they have the best prices or are a reliable store
(or what brand parts they are selling). To do the front and rear
suspensions, I got a shopping list of (numbers rounded):

Front:
Coil spring (right); qty. 1, $63
Coil spring (left); qty. 1, $63
Strut (right); qty. 1, $105
Strut (left); qty. 1, $105
Upper strut mount; qty 2., $53 each

Rear:
Coil spring; qty. 2, $63 each
Strut (right); qty. 1, $108
Strut (left); qty. 1, $108
Strut bumper; qty. 2, $24 each
Strut dust shield; qty. 2, $14 each
Strut mount (right); qty. 1, $86
Strut mount (left); qty. 1, $86

If I got all the parts, the front would cost $428 and the rear would
cost $549 (for a total of $977 for all four corners). Now I see why
the shops were quoting their prices around $1200 (I forgot to ask them
if it included the alignment). What I'm wondering is, if I do this
myself, how to determine if I really need the coil springs and strut
mounts.

I've been recommended to go to a body shop to have them measure the
ride height (unloaded) which would indicate if the springs were
sagging? Is that true? Is it an adequate test? All 4 struts were
replaced 5 years ago but not the springs so the springs are the
originals that are 14 years old. Bouncing on the corners won't tell
me how good are the springs, just maybe how good are the struts.

When taking it apart, how would I know if I need the strut mounts
(i.e., the plates at the top with the sleeve bearing)? Could I tell
if they were worn? Could I tell if they were loose (i.e., so the top
of the strut wobbles around)?

Could be to do a decent job that all these parts need to be replaced.
At that point, I'd rather pay the extra $230 (both front & rear) to
let the shop do all the grunt work. But if I don't need the springs,
strut plates, and strut bumpers, I'd chop $232 off the fronts and $346
off the rears (or $578 total saved, or a total expense in parts only
of $477). The difference between $1200 (parts & labor) and $477
(parts only), or $723, is enough to make me plan on doing them myself.
I'm not sure what the shop was going to replace (i.e., if they might
try reusing old parts) or if all the parts would get replaced.

Likely the springs are OK.
Anyway, you could try OEM at discounted prices from
www.subarugenuineparts.com .
Also, www.boxer4racing.com (and other sites) have SOME aftermarket parts
for legacys (like KYB struts) I think.

Prices there are always higher because all I find for parts are the
performance parts. Not interested in lowering or stiffening my ride.

Mostly performance parts again. Springs that lower. They have a KYB
4-pack for struts looks okay for price.

Oh yeah, springs from a low mileage wrecked vehicle might be a good
alternative for you. Not the struts though.


Yeah, we have a U-Pull-R-Parts place (2 sites) in our area that are
handy to go grabbing parts off of (http://www.upullrparts.com/).
Already got a fender (still need the other one), hood, and both
headlamp assemblies from them. We didn't have the tools to go after
the springs. They do put them up on blocks (well, they're steel
wheels welded together so I'm not crawling underneath). Since these
yards only carry cars that are over 10 years old (so mine qualifies at
14 years), the mileage is high enough that I don't go for the parts
that wear. The Subies that I saw all had over 50K on them. Trying to
find Subies at the other yards has been fruitless so far except for
one 150 miles away.
 
Try 1stsubaruparts.com they have Genuine OEM parts at awesome prices.

Just from a quick glance for the front -

Front strut - $83.96
Spring - $44
Mount - $41

As for being able to tell whether it's worn or not - depends on mileage
and where you live. Suspension parts tend to get rusty

Try emailing Jamie through subarugenuineparts . She's great and can
probably help you. The site is kinda odd in that they run 2-3 seperate
catalogs and the springs you want are likely in the crash repair
whatever catalog.
Or, try posting a WTB (want to buy) over at www.nasioc.com and someone
who is upgrading their suspension would likely sell their stock takeoffs
cheap. Someone may even have some laying around already - check the For
sale ads too.
The KYB struts are, I believe, direct replacemnts - not really
'performance'. Though, keep in mind, even new stock parts will likely
feel much 'stiffer' if the current gear is worn out.
