Frame hole drilling

Where do you drill the frame to keep water from collecting?

Bump. I assume the lowest spots on each rail.

Below the rear lower control arm is a popular spot as it is a very low point that is plagued by buildup and often is the first portion to rust out and fail.

You will want to drill drain holes in the low spots of the frame. Just crawl underneath and look at the frame. Put a hole anywhere you think water would collect. Remember to make it large enough so that it does not get easily clogged with rust flakes and mud. 1/4" bit is a minimum. U will probably be surprised how many rust flakes there are in there. I have a Snapon flexible inspection camera. Scary to look inside and see all the flakes. U can stick a small hose attached to a shop vac in on of the large holes on the side of the frame then used compressed air to blow the rust flakes to the vac hose. Takes a while but u can get it pretty clean doing that. Then treat it with a internal frame coating like the one Eastwood makes.

Another area to close attention to is where the center skid plate mounts to the frame. I have seen a lot of jeeps rot from salt and water getting between the plate and frame. I took ours off, cleaned, prepped, then painted both parts.

^+1....after reading all these threads on this subject I vacuumed out the inside of my frame rails using a shop vac and some rubber tubing, drilled a .250" dia. hole just ahead of the rear control arm on each side, then used the Eastwood Internal Frame Coating....didn't have any major rust yet and I want to keep it that way. If you ask me this is one job all TJ owners should do regardless of the frame's condition.

Got to say that looks like about the best thing I have seen that would be worth trying out. Actually having a hose long enough to apply it where it needs to be......brilliant.

I drilled 1/2 inch holes in the bottom side of my frame by going through the slots/holes in the LCA brackets and just went straight up. Just need to have a long enough bit. I figured any compromise of the frame would be lessened by going to a spot that is re-enforced.


From all the pics and the numerous frames I have seen personally that is the spot (especially the rear) that stuff will build up at and sit.

How much of this would you need to do the full inside frame?

Awesome! Thanks. Can anyone point me toward a good thread that details a full inside and out frame cleaning and coating video using Eastwood on jeeps (body on). I'm looking through the search but its somewhat scattered. As soon as my jeep is out if the transmission shop I'm going to drill and treat the frame.

Yep- 3 cans will cover. This stuff is awesome and ridiculously easily to do.

I was wondering if anyone has done this long enough ago to tell if it is effective?

Still haven't done it. The rain this year has been crazy so I'm waiting on a few solid days without rain to throw it in.
