due to the desire of the Stateboys for diesel 70s and especially the LHD configuration sometimes ... the rose-colored glasses can come into play.

this post should help those individuals that are interested in buying a 70 series.

i have been contacted by individuals from Mud about 70s that come up for sale, especially over the last couple years since they have become importable to the States.

if it was me that was interested in purchasing a diesel 70 in Canada, i would want to know exactly where to look for bodywork. i would want to look at the truck in person or have someone you can trust to look it over.

i would recommend this even if you are interested in one of my trucks, get someone neutral to look it over. someone that KNOWS 70s or look at it in person.

this thread will show you where the 70s rust, these are the areas to look at if you are considering buying from Canada, East coast, West coast or anywhere in between:

this was an extreme example but it show very well, where to look for rust and / or body work.

treat every truck sale as a scam, always go with your gut feelings ... if something seems too good to be true then treat it as such.

-have the seller pull the inner panels to see the joint between the inner wheel well and the outter fender.
-lift the carpet and the retainer to see the rear floor to rear sill joint.
-lift the carpet under the drivers and passenger foot area and look for rust, seam sealer, paint (or lack of it).
-look at the rear body lip just in front of the rear bumper where it meets the inner fender, same with the front section of the same inner fender, the 70s rot there because of overlap.
-check the frame next to the factory muffler location, the salt sits in the frame and the heat from the muffler keeps it active
-check the front frame horns and especially next to and between the steering box for soft spots in the frame
-check the shackel mounts to the frame at the rear of the rear springs
-especially check the lower windshield frame both inside and outside since these frames love to sweat and rust.
-check the A pillars both at the top outside and the inside near the joint about half way down.
-check the overlap joint of the sill outside and below the rear front door corners, the bottom of the B pillar, is prone to rusting.

a joint should have a divit that shows, usually bodywork hides this divit or groove.
a joint should have seam sealer installed.

take a close look at the rusted areas on page two, and print off the pics, of the link, it will give you an excellent reference for when you lose track of that vehicle you are looking at.

remember, it is easier and cheaper to walk away from a questionable rig than pay and keep paying as the repairs add up. scam artists come all nationalities, they can own their own dealerships, companies or be a curber. i have met completely honest curbers and licensed thieves, a piece of paper means nothing.

i hope this helps those shopping for a 70,

(feel free to add points that you feel is important for those desiring a 70.)

Another spot where 7* series like to rust is on the door ,near the hinge mounting. Its easy to miss and a difficult repair.
Also on the firewall where the top half meets the lower half.Once you get rust in there it travels along at a frightening pace.

On warm sunny days,after its been raining,I like to open up all the windows and doors and allow the body to dry out.
 
thanks Rosco

also on the hard top, 70, 77, 78, 75 troopie and 79 troopie that have AC, check carefully along the gutters for small amounts of rust, that means there is a lot of rust hidden behind the metal

you take a look along the gutter from front to back and look for bumps under the paint or actual rusting. it will be where the gutter meets the roof or even along the bottom of the roof curve.

you can also get the rust under the gutter against the side wall.

This is why I like to ventilate the interior when its warm and dry.
 
Another major issue that is seldom addressed when U.S. citizens buy "questionable" 70 Series is the lack of parts. There was a 70 Series recently for sale on MUD that was already in the U.S. that had significant rust issues and the seller said the rust issues were "easily repairable". With all due respect, at best this is misleading and at worse it is an outright lie. Granted if you have unlimited resources and own a machine shop than the "rust issues" may be easily repairable.:bang:
 
good point old feller,

rust issues are NEVER easily repaired. they are just easily hidden.

The old saying that you only see 10% of the rust is unfortunately accurate and something potential buyers should keep in mind.
 
Bump...Maybe the moderators can put this topic at the top of the 70 Series page with the Manuals, Meet and Greets, and Registry.

Great write up by Crushers.
"Go Fast" also had a great buyers checklist a few years back in 2015, as well. Here it is:

Rear "rocker" and pinch weld behind the rear wheels is a trouble area, so is the rear wheel arch. Check the windshield frame for rot too. The 13BT factory turbo's need attention early - expect to pay to have them rebuilt. Find out when the injectors were done last too.

Look for frame rot on the round tubular cross member.

If for any reason the head was off, find out it they used OEM gasket or not. I've seen two aftermarket failures in the last two years.

Jack up the truck and look for excessive play on wheel bearings.

Wire hacks etc - avoid 12v taps

AGM batteries in 24v with 12v converter systems don't do well the loads don't balance right between batteries. It took me two sets before I figured out that they failed early

Pull the tail lights and look in the body cavity - might be able to tell if its been hit and had an accident or not. (Also you can see if the electrical was tapped for a trailer)

Check to see if door panels line up with the body.

Don't be distracted on the coolness - look for missing clips, covers, bolts etc.

In addition to Crushers and GoFast comments, I would also like to add, I found a relatively rust free, but high mileage, 70 Series. Top on my list were LHD and Coil Sprung. I was sort of awed when I finally found one, and by that fact that it had little rust. I thought I had done my due diligence. That said, I didn't do a thorough inspection of the electrical. All the lights and high beams, and turn signals were functional. So I didn't really second guess it. One big "Red Flag" on the electrical should be a electrical connection for a trailer. I saw the connection, and thought it was a "bonus" at the time. However, I have a nightmare behind the rear quarters and under the bumper due to a "hack job" electrical connection for the trailer.

Great thread for us new bj owners. Rust here in Winterpeg is nefarious. It's the cheesy repair jobs that make it worse. You can never rid a vehicle of rust once it invades lap joints etc. what is the best stabilizing product? Inspecting vehicles is tricky. Because....."when the f*%< is on da brain is gone" we tend to minimize what doesn't agree with our wants. "Oh that's just surface rust"lil rust hole took me 15 hrs to fix. Woulda been a grand in a shop. Rust isn't like a bad tranny. Can't easily replace the body.

Another place I like to check for rust requires you to get down low and look up at the seam where floor meets the rocker panel. Its a kind of a litmus test. If there is no rust in the seam its often a good low/no rust body overall, but no guarantees.
