Q: new shocks/struts - when?

I can spare you some if you'd like! Just tell me how much you need!

I have to do the struts on the Supra; I have 'new' (~20,000 miles) springs, but was told by an alignment tech the bushings were worn. Oh, boy!

Do you get a lot of headaches?

The Supra shocks might also be made by KYB. It's stamped right on mine anyway.

I'm kind of surprised your Supra would need much suspension work. Mine has not been touched from day 1 and I kind of abuse it. Tires even wear perfect still.

I'm 6' 2" and 180 lbs. I used to be 170, but then I started working from home and was too close to the kitchen. :(

I'd kill to be 180 again!

There's a bit of play in it. Not much, but enough to make it difficult to align.

As long as the susp. bolts don't break, it should be pretty easy. The only thing is, if you're going to do one side, you should do both. And I may go Polyurethane for a bit stiffer susp...

I haven't seen a hard copy manual in a while but sometimes there are specific supplements to the main, such as the electrical, chassis, body, emissions,ect,. It is impractical to remove the spring for a height check. There is a measurement and method of measurement for the vehicle that should be mentioned somewhere. You may not have access to all the information. Terminology is at times different between each manufacturer. I've seen it called running height, curb height, chassis height, something along those lines. I would only trust an accurate measurement in an alignment bay. The rails and pads are set up perfect. You might want to ask the person working the alignments at your dealership. They should know and/or have ready access to specs and how it's done on your car. The "bounce test" on a strut is only valid if the correct spring energies are present, and the specification for that energy is usually in the form of a measurement. Not to have an engineered and tested specification could at a point, allow the vehicle to encounter adverse chassis handling effects that could be very dangerous, and lawyers are everywhere.

The ONLY two ways I know of to truly "test" or diagnose shocks are to run them on a shock dynamometer, OR to take the vehicle for a ride.

Hit a rough road, some railroad tracks, some dips, "S" turns, a nice, smooth road, hard acceleration, hard braking, etc.

The old standard "bounce test" - where one bounces a corner of the car then sits back and counts the oscillations - is really lame. It only generates enough shaft velocity to "test" the fixed bleed orifices and devices, and within-spec. seal blowby.

Bouncing the car gets the shock/strut shaft moving at approximately one inch-per-second (ips).....MAYBE!

Driving down a smooth road and turning into a smooth turn moves the shock/strut shaft at approximately four-to-six ips.

Hit a pothole, and we're talking 10-15 ips of shaft velocity.

Bouncing the car doesn't even open a single, low-speed valve in most shocks/struts. Forget about the high-speed stages and valving.

I regularly show customers a shock moving at two ips on my shock dyno, and they cannot believe how fast it actually is.....and the shock is really not "up on the valves" yet at those shaft velocities.

Unless a valve is actually broken, it will not show up in a "bounce test", so a shock/strut could easily pass the "bounce test" and still be a dangerous piece of junk.

No, really. I'm just a bit surprised there are no specs at all for ride height.

Every other suspension setting is there, even stuff that's not adjustable, but not ride height.

There is a specification for ride height somewhere, because I've had to look it up. It is not listed in a convenient place where one would expect to find it. I think it was in the body repair manual or alignment specs.

Not for any Honda I have access to documentation for.

I have literally every other spec, including densely detailed frame repair schematics, but no ride height. The only height information available is the overall height to the highest point of the roof.

In the '93 Previa and '97 Avalon factory service manuals, the suspension height is in the Steering and Axle section as an alignment specification.

Do you have the Previa service manual, or is this just top of the head info?

Here's the deal: supposedly, one of the Previas came with dual-piston calipers, and they will bolt right on to an '88 Supra...

Hmmmm....

Previa AWD w/ABS-Dual Piston Caliper...

Hmmmmmm....

The info is not off the top of my head - my memory isn't that good! The '93 Previa Factory Service Manual lists 2 types of front calipers but it doesn't list application, i.e. whether it is on the AWD with ABS or not. The AD45T type front caliper does have dual pistons but it is not a full floating caliper - both pistons are on the same side instead of one large piston.

I checked there too. All my alignment specs are there. Ride height is nowhere to be found in my very thick factory shop manual, believe me.

Maybe they added it later, but the FSMs for the '96 Odyssey, the '00 TL and the '06 CR-V list it in the "dimensions" block in the Spec section at the front of the book. Honda calls it "ground clearance".

2 more questions:

  1. Would worn struts/springs affect how quckly the wheels get out of alingnment?

  1. Will I need to get alignment done after replacing the struts/ springs?

thx

Yup! That's the one. From what I have read it bolts right onto the bracket on an '88 Supra, no modification required.

Part of me wants to do this, and another part of me says "the brakes on the thing now could send stuff flying around the cockpit no problem!"

I believe you ;-) It seems like a pretty big omission on Honda's part.
