Front Evo shocks coming loose.

Anyone have issues with their Evo shocks staying tight at the knuckle? Yes I'm using shims and I haven't done anything different from anyone else that has done the conversion.

I drilled mine out and used the EVO factory bolts. I haven't had much of a problem, but I was suspecting some issue with camber and was thinking they are moving. I noticed on the alignment rack it's set to -1* camber, yet the outside of the tires are wearing much faster.

Blew the trans before I could investigate though.

I drilled mine out but I used some grade 8.8 bolts that have course threads. I'm using lock washers on both sides but my driver side is coming loose. Do the Evo bolts have fine or course threads?

If the say 8.8 thy are only slightly above SAE 5. Stock Galant bolt in this position was grade 10. Get stronger bolts!

I don't have an evo but based on the way Mitsubishi threads things I would assume m14x1.25

You need hardened washers and lock rings too. Otherwise they mushroom out on the holes and allow the bolts to loosen up.

What are you calling lock rings?

I don't know if the washers are hardened. I also used nylon sleeved lock nuts. Maybe I just just order a set of evo bolts.

I need to check what size drill bit I used to drill out the hubs, I can't remember off the top of my head.

Grade 11? Where did you get that?

Typically, fasteners with the highest tensile strength would be grade 8 for SAE and 10.9 for ISO. Never heard of a grade 11 fastener before /ubbthreads/images/graemlins/dunno.gif

stock turbo to manifold bolts are grade 11 /ubbthreads/images/graemlins/dunno.gif
They are camber bolts mine are 12mm. got them at the part store. They may say 10.9 on them, But I'm pretty sure they said 11. Anyway its a bolt engineered to do the task were talking about here and I'm confident it will work as a solution for your problem.

The flywheel bolts are grade 11. I don't know about any of the others.
