Tokico fail
 
6 of 8 hours on the road was completed on this blown shock:
http://i34.tinypic.com/msli8o.jpg
highway 69 in OK is bumpy as hell and I guess a couple hours of rhythm kill't it.

fooger03 08-17-2010 08:49 AM

You're should have got the red tokicos; the white ones are for riding lawnmowers.

hustler 08-17-2010 08:53 AM

I guess I'm putting Bilsteins back in with stock springs.

ThatGuy85 08-17-2010 09:13 AM

Note to self: Do not use white tokico's...

Braineack 08-17-2010 09:16 AM

I don't even see how you can snap the shaft like that... it's traveling up and down.

18psi 08-17-2010 09:20 AM

he used the shaft for other purposes

levnubhin 08-17-2010 09:22 AM

Something had to have been left loose.

I've been on the same shocks for 2+ years now.....

his anus was loose

Braineack 08-17-2010 09:31 AM

i could see this happening if the top bolt wasn't secured, and then the shaft popped under the mount and got stuck at a weird angle and eventually snapped

swingdancr 08-17-2010 10:11 AM

If you were the original purchaser, and you have your invoice where you bought them, you can return them to Tokico for some $$$.

Check out the last page for their lifetime warranty details.

MartinezA92 08-17-2010 12:13 PM

I'm going with the top being loose. On that note, I hated the Tokicos.

mgeoffriau 08-17-2010 12:19 PM

Dogpiling, but yeah, how would any lateral force be applied to the shaft unless one end or the other was shifting under load? How massive of a metallurgical defect would there have to be for it to shear in two under vertical force?

Everything is still tight, not sure what happened. Please pm me if you have stock springs to sell me since that rear is bent severely. Thanks.

webby459 08-17-2010 12:46 PM

^I don't have new springs for you. But...

I thank my lucky little stars that your manly physique was not harmed in any way when you had your trouble.

99mx5 08-17-2010 02:09 PM

I thought you had Tein FLEX shocks.

I'm assuming this is his daily driver. Either way - I loved my Illuminas and never had problem with them. Used them on multiple different cars over the years without a single problem. I bet that you fucked something up as usual.

jeff_man 08-17-2010 02:19 PM

mhm i'd just keep driving it

You are right. I didn't notice the color of the wheel well. I fail!

why are updates to this thread being emailed from "notifications@miataturbo.net" instead of "webmaster@miatatubo.net" like the rest of them....this is severely fucking up my email auto-sort feature - ARGH!

Braineack 08-17-2010 03:40 PM

if i got emails for all subscribed thread, I'd break google. not sure why it changed...

mgeoffriau 08-17-2010 03:43 PM

I thought everyone just clicked "New Posts" every 30 seconds like I do.

Quality Control Bot 08-17-2010 03:43 PM

Might be due to the mobile reply. I am sniffing around to see whats up... *sniffing*

Braineack 08-17-2010 03:46 PM

Thanks Rick.

gospeed81 08-17-2010 06:43 PM

LOL

I don't know how the hell you did that...but it's awesome.

I, like Brain, am having trouble understanding how this thing failed in sheer...I mean without being bolted to a Volkswagen with no springs and bolts as camber shims.

jeff_man 08-17-2010 06:49 PM

hustle is really just a 600lb black woman, all that extra wight is hard on suspension.

I knew it!

I always knew there was something up...white men don't have government jobs.

ZX-Tex 08-17-2010 06:59 PM

I agree. Awesome failure.

It is not necessarily a shearing failure because of the way it is oriented in the photo. That could just be the way things ended up after it let loose.

I would really like to see a high resolution close up shot of the failure surface. That could offer some clues that probably only I as a ME geek would be interested in.

Assuming no binding at the mounts (that would have created a moment load) it could have failed in tension since the shock is what limits the travel in extension. But then again, the front end has to be completely unloaded, quickly, to create a significant tension load. Were you catching air on some of those roads? :giggle:

It could also have been a compression failure initiated by a defect.

Are you sure the spring was seated properly? It looks OK on the bottom perch from what I can see.

juxt3r 08-17-2010 07:07 PM

That's a pretty impressive shock failure you've got there. If you need a temp replacement, I've got a set of (used) NA AGX taking up space in the garage.

so true

Doppelgänger 08-17-2010 07:52 PM

How long before Hustler is riding no Ricelands :giggle:

y8s 08-17-2010 08:28 PM

what kind of top mounts were you using? there are some questionable rigid ones that I've seen that look pretty weaksauce.

hustler 08-17-2010 09:25 PM

There are stock nb mounts. I'll get shots when I swap them out this weekend, and I'll also getthe pipe cutter out and gut te shock because I've always wanted to see the insides of a twin tube after lookig at a bunch of monothbes. I guess I need to call Bernie at Stewart Development together my Bilsteins revalved for stock springs. It looks like ice secured a temporary set of shocks for the time being but I want to get properly valves shocks in this car for daily surfing in style.

I was pretty impressed to see that damage from the rhythmic bumps of US69 in Oklahoma, but I assume this is a fatigue failure rather than failure from one impact.

JasonC SBB 08-18-2010 12:48 AM

For stock springs just use NB HD's. They're pretty well valved. You'll need the NB shock tops as well.

Werd.

Next to Teins this was my favorite setup...really.

I've got a set of stock shocks with a set of Eibach springs on them.

$100 plus shipping. LMK

PM'd about a stock spring. PM me back in the next hour or so and it'll be in the mail today.

hustler 08-21-2010 05:09 PM

Any thoughts on Bilstein HD's with stock springs?

Levnubbin,
How many miles on those shocks and are they NA or NB? I might take those with "express" shipping.

Thanks again for the offers everyone.

chicksdigmiatas 08-21-2010 08:37 PM

If you could grab msm suspension, that would be win.

hustler 08-21-2010 08:47 PM

I just came home with MSM springs...so considering I have Bilstein HD's, NB front mounts, FM rear mounts, 37mm FCM stops, and MSM springs will I have a comfortable ride and reasonable ride height? Should I try to run the stock springs if I can? I plan to install these in the morning.

chicksdigmiatas 08-21-2010 09:33 PM

Mine sits about a half inch lower with the full msm suspension. It rides great and still has decent firmness. Its just stock but better.

Na shocks with like 80k on them.

That's just what I wanted to hear. some told me the rear springs were much longer but it sounds like I'm in business. I'm about to go start on this after I drink a few dozen cups of Blue Mountain.

lordrigamus 08-22-2010 01:37 PM

Bad shock, great coffee.

I am not at all pleased with my Tokicos. Mine are already sagging.

Granted, the sport shocks and springs are a cheap, entry level setup but I wouldn't think they would be sagging after 10,000- 15,000 miles. The car has never seen any track time and the roads around here are relatively smooth.

Perhaps the premium ones are better but I'm leery of their products because of my experience.

levnubhin 08-22-2010 03:45 PM

You got the blue ones?

Yes with matching springs. I no likey.

They still dampen ok but the springs are shot.

gospeed81 08-23-2010 07:50 AM

Hustler, are those HDs NB or NA?

I used MSM springs with a set of NB HDs for the better valving, but it was at least at stock height, if not higher. Been so damn long since I don't know what stock looks like anymore. Same setup with stock springs looked like a monster truck.

Of course my car wasn't a loaded street pig at the time (no interior, A/C, PS etc)... and I'm not a 300lb black woman.

hustler 08-23-2010 07:54 AM

Na HD's. BTW, The NB springs are too tall and now I have 4" wheel gap in the rear.

I have a broken CV-joint boot too. Any thoughts on how I should go about replacing that?

When I get home I can check my notes and get you a cut coils/ride height ratio.

I had to take off a lot more than I thought I would with the MSM springs to make it decent...like 1.25F and 1.75R.

I'm also guessing you found a set of NB spring perches for those open ended springs?

If not I have a Bilstein set I can send on the pronto. Let me know by midday and it'll be at your pimppad tomorrow.

Been there. Had to switch back to NA springs but the NB Bilsteins I put on are nice. I had to use the NB tophats, too.

depending on how bad it is, if its clicking I"d just get a new one.

otherwise I throw some duct tape around the tear until you can get a replacmenet boot and pull the axle. How I did it until I could replace my boot

hustler 08-23-2010 11:22 AM

I have NB and NA perches lying out, and FM rear perches.

The CV boot is torn, nothing more. I may try to "bag-it" rather than replace it.

Its amazing how much better the Bilsteins are than the Tein Flex or Tokico's for daily driving. Monotube for life. I wish I had the money to buy FCM shit for my track car, but I'm poor.
