My quest to fix Yonaka coilovers

[Nikko]

Hi all,

I recently bought some used Yonaka coilovers for a decent price, considering one of the shock cartridge is shot.

I understand that these are super cheap coilovers and that you get what you pay for, bla, bla... Well, I'm on a super cheap budget, and one thing that anoys me more than not having money, is clearly wheel gap.. lol.

Yonaka themselves wern't really helpfull at sourcing a replacement, wanting a premium on the part and having a delay of a few months.

While doing some reasearch on the subject, I stumbled upon something... You be the judge:

What is not cool with Yonaka is that they claim to be the manufacturer and that their coilovers come from Japan.. Really?

Anywho... This is still a work in progress and I will add any usefull information I find as I work on this in the future.

**Update**

So today I finally was able to remove the dust cap off of the shock cartridge. Note that these are a twin-tube configuration. The dammage assesment has led me to conclude that the inner tube has been deformed, and has cracked under the pressure; obviously due to the lower quality material used.

The taiwaneese manufacturer has yet to respond to my e-mail. In the meantime, I will look into sourcing a replacement tube, that I could get cut and threaded... Maybe.

Even stock struts and cut springs would be an improvement over spending ANY money on those piles of garbage.

Save yourself some trouble, and toss those straight into the trash can. Then build your own setup with Konis and GC sleeves.

Read it as many times as you need to until you understand it inside and out. Then hack up some casings, get some inserts, and get low with quality. If you source your parts properly, you will be in the project under $1000.
