OK the diagrams are a bit confusing.

Do I need to order 4 or 8 bushing to restore the DTSS system? There's 2 part numbers listed as shown here:

FB01-26-410C
FC01-26-410


I almost ordered the entire DTSS HUB which is $100ea x 2.

Here's the full diagram:

 

the aftermarket solid ones are one bushing on each side. you can't buy the stock ones unless you buy the whole hub

 

According to Henney Mazda's parts department I'm ordering JUST the bushings, not the whole hub.

I believe this is all you need to restore the OEM DTSS system. Can someone confirm? The bushings are not integrated according to the diagram above.

Here's the part number:
Qnty 4 FC01-26-410

 

as far as I know mazda doesn't sell the bushings alone and you need to buy the whole hub with pre installed bushings.

if you phone and try to order that number they might just tell you they no longer exist or something.

 

I'll check with the dealership tommorow then and see if the order went through as is.

The DTSS HUB would have been $100 x 2, whereas the bushings I ordered were $9.10 x 4.

 

Like Scott, I didn't know you could order them without the whole assembly, but from your diag it looks like you can.

From the diag it looks like you need to order the "26-141A or Y", you should need 2 only. The "26-410B"'s are just the dust caps on the ends, hence why you are seeing 4 per side.

why replace the DTSS? when you can just get rid of it? My car handle so much better with the rear toe eliminators installed, it has a much long threshold before breaking loose in a turn and when it does its easily controlled....

 

So your saying the FC01-26-410 "Rubber-Seat-BRG Housing" is really just a rubber dust cover?

According to the dealership & this diagram,
26-141A and 26-141Y ARE the HUB Assembly as shown here:



FB01-49-130 - Hub(right), toe control -outer
FB01-49-140 - Hub(left), toe control -outer

If you know how the DTSS works, you can use it to your advantage. Plus I believe the aftermarket eliminators don't come in rubber only harder materials.

These are $100/ea x 2.

 

Yeah, the 410's are not what you want.&nbsp Those are just the rubber caps from each side.&nbsp The part you want is the part pictured right under the "26-132C" box - this is the actual DTSS bushing.&nbsp It looks like you can't order just that part.&nbsp The set is either 26-141A or 26-141Y.

Yeah, why you want to restore the DTSS?&nbsp It'll probably be easier to steal a set off a stock car?

Ted,

Thanks for replying. Yeah if I "connect the lines" in that diagram, you have to order the whole $100 x 2 parts set to get it Don't see a seperate part #.

I'm restoring the DTSS because there's no aftermarket rubber bushings or rubber eliminators that I've seen. On the convertible, I'm keeping the OEM soft (no noise/harshness) suspension.

If your curious, here's the prices I'm being quoted in general (how harsh is the cheap polyeurethane again ) This is what I've read wears out first. I'll inspect the engine & trans mounts as well when I'm tearing into the suspension. (my TII needs engine & suspension mounts - kaclunk kacluk)

Rear
$24.60 x 4 FB01-28-460 Trailing Arm Bushing - Triaxial Flaoting Hub Inner Side
$24.60 x 2 FB01-26-220 Trailing Arm Bushing - Subframe side
skip ($70 quoted) FB43-28-840 Subframe rubber mount
$100 x 1 FC01-28-980 Differential Rubber Mount
$6 x 1 FC01-28-896 Differential Rubber Mount Rubber Washer
$3.75 x 2 FB01-28-156 Convertible Rear Stabilizer Bushing
$100 x 1 xxxxxxxxx DTSS rear toe steer bushings - Right Side
$100 x 1 xxxxxxxxxxx DTSS rear toe steer bushings - Left Side
$5 x 4 FB01-26-250 Pillow Ball rubber seals

Front
$19.20 x 2 FB01-34-470 Lower arm bushing - Front
$24.60 x 2 FB01-34-460 Lower Arm bushing - Rear
$5.60 x 2 FB43-34-156B Stabilizer Bushing

 

i think on mazdatrix's site they say that the dtss elim bushings dont increase noise/harshness of ride... since they are insulated from the rest of the body by the subframe bushings... so long as those are rubber i think you will be ok...

 

The mazdatrix eliminator bushings didn't add noise or vibration to my ride. however, it did greatly improve the control that i had over the vehicle. I tried replacing the the stock DTSS system, and it was a complete waste of my money, and time. Far easier to autocross without the system.

 

So even though the Mazdatrix / RB bushings are polyeurethane, it shouldn't introduce and NVH (noise vibration harshness) into the car then ?

Ah shucks, just when I was use to using the DTSS.

 

Yeah, my experience with the DTSS (RB part) eliminators is that they do not increase NVH.&nbsp If you can understand the KM hub, the forces on that particular bushing is in a weird plane.&nbsp The solid Delrin (I don't think it's PU) bushing should actually decrease noise, as the stock piece slides quite a bit in a "slot" in normal operation.&nbsp Go with the RB bushings - I don't think you would be disappointed.

I just recently installed the delrin toe elim. bushings and I think you'd be making a serious mistake by not getting them. My original bushing was totally destroyed. The tire was able to toe it self out at the slightest of movements. If your stock bushings are in a similar state, you're going to love mazdatrix's bushings..i think they were 40 bucks.

 

Therx7ist,

The problem is nobody is comparing the stock new bushings against the eliminators. The worked for ~75K miles pretty well. Yes any replacement will be an improvement over wornout bushings. I'd like to keep the OEM setup, but I can't see spending $200 for a hub. I did call Mazda and the operator is researching if Mazda can sell JUST the bushings for cheap.

 

slightly off topic... but does anyone know how to determine if the stock ones are bad or not?... any good way to check and positively determine that the dtss bushings are the cause of a rear instabliity problem?

 

Put in on jackstands & push against the rear tire. If the tire moves even slightly foward or backward....

Granted new springs, struts, alignment, & balance will make a WORLD of difference. Bushings just help "tighten up" everything.

 

Mazdatrix explains why the DTSS bushings aren't available directly:

place hands on top & bottom of tire and push/pull.

somebody should go and make a collection of all the ways to diagnose suspention problems on our cars....

maybe ill do it if have some time on my hands
