Rust

When I bought my wrangler the bottom was rusty and a few hinges. Is there any thing I can do to clean it up underneath? The hinges I'm sure will have to be replaced.

With POR 15 you do not have to clean all the rust off before you apply the coat. I have used it on the frame and underside of the body and it works good. It just is not cheap.

To an extent, you need to wire brush the scaly stuff off. The more the better.

Ok! Thanks! Have either of you changed the hinges or looked into it? Is it very costly?

Door hinges I'm assuming? Those are not too expensive to replace, I replaced mine when I bought my jeep. I can't remember exactly how much it cost, but i think something like $50 per door. Do some ebay searching, you'll find what you need.

Is it simple to change them myself? And I apologize for such a late response! I do appreciate your help!

Hinges are easy. Are they rusted through? Do they just have surface rust? Any pics? What about the tub? Any rust under the pedals? Did ya look? Very popular area for rust to hang out....

I just bought a 2011 with 15kmiles and my dad has had keeps for years. I thought I was rust free but he showed me rust starting in alot of places and just told me how to spray it and stop it.

We live in Massachusetts and there's a to of salt in the winter.

Have any of you welded a plate over the hole behind the front wheels ?

My dad showed me this hole that he says when you turn the wheels that water and salt can get in but it can't get out and it gets stuck in the frame so he welded a plate over it.....

Anyone hear of this?

What hole you talking about? The one by the gas/brake pedals on the floor? Or inside the wheel well somewhere? Don't think there is *supposed* to be one there! lol

These holes

The mechanic said its been an issue for years. The water/ salt combo gets shot in when you're driving and never gets washed out.

My fathers tj has the holes and my JK has them too.

Those holes are a PIA. Non idea why they are there. The problem is mud, sand, and salt (I'm in mass too) gets into the holes and pools in the low sections of the frame. There it rots trough and eventually your frame is junk or needs repair. This is what I see as the best course of action.

First. Clean the frame inside and out. Park your jeep on as much as an angle as you can and then put a hose to the holes. Get any dirt or sand out of there.

Second. Coat the inside of the frame with Eastwood internal frame coating

Third cover the holes on the side of the frame

Last. Drill some drain holes of your own in the low portions of the frame.

You will find posts in this site for each step.

You might also want to cover any other areas under there with bed liner or rust inhibitor. Body mounts, motor mounts, ect.

Ford Trucks have them in the same spot (crumple zone) however they have holes in the bottom and side of the frame for drainage as well

You can still patch them. I wouldn't weld them shut or anything but patch them with a light pliable material which won't interfere with the "crumple" aspect.
