Ball Joints 2.0

In my last post, covered the Chrysler style screw in ball joints commonly used on Mustang II front ends. Today I want to talk about the Dakota ball joints and some misconceptions being run around the internet. There are a few generations of Dodge Dakotas now, I concentrate on the first two, being 87-90 and 91-96. Both are pretty much the same, the ball joints are exactly the same.

I have run across a few people trying to conflate the 97 up (3rd Gen) Dakota ball joint issues with the earlier First and Second generation trucks. In the 3rd Generation Dodge made quite a few changes to the Dakota’s front suspension. Almost a complete redesign. About the only thing similar is the lower control arm spacing and bushing size (yes, they will fit our kits) and the upper control  arm rear mounting bolt is in the same location. But that’s it. The rack mounting and angles are very different and the upper control arm became symmetrical for cost cutting reasons. The other major changes are in the spindle and ball joints. They bare no resemblance to the 1st and 2nd gen trucks. The ball joints became significantly smaller and the orientation of the lower ball joint changed from tension (pointing up) to compression (pointing down) making dropped spindles pretty much impossible.

 

Have a look at the line up of ball joints here. From Left to right, the 1997 and up Dakota/Durango ball joint, The K772 Ball joint used in most Mustang II type set ups, The K778 joint used in the 87-96 Dakotas (and many other full size cars and trucks) and then on the Right is the K7025 used on the Dakotas and several other full size cars and trucks. Visual confirmation would show you, this is robust stuff. History can confirm that these larger ball joints were not failure prone. Sure, everything wears out, this is why we recommend using premium quality repair parts when building your car or truck. Not only will you see a longer service life, you will get a better ride quality with parts like the MOOG joints and bushings we suggest.

I suppose shocks would be the next topic, stay tuned!

Ball Joint talk

What I wanted to discuss is regarding the screw in MOPAR style ball joint that is very popular with the tubular control arms for the venerable Mustang II suspension.

These two ball joints are very different in how they are supposed to be used

The ball joint pictured at the right is the commonly used K772 MOPAR screw in ball joint used on tubular control arms throughout the industry. If you look up that number you will see it is meant for MOPAR Upper Mid-Sized cars. It is not intended for use as a lower ball joint where it will see tension loads.

The ball joint on the Left is a K719. It has the same threaded body of the K772 but if you notice one very different difference in that body, it encloses much more of the ball stud. This is a true lower ball joint meant for the Mid-Size and larger passenger cars. While it will directly replace your K772 ball joint in the control arm, the stem is larger. This larger stem requires you to machine your spindle to accept it.

While many thousands of cars and trucks are on the road using the K772 as a lower ball joint without failure, we have seen a few. Granted, this is a very robust ball joint, and if you are using a quality joint like the MOOG Problem Solver line, you may never experience a failure. We have, on the other-hand, solved some driveability issues associated with the Mustang II suspension, mainly the nervousness out on the highway but replacing the ball joints with a true lower ball joint. Now don’t take this as the end all-cure all solution to your Mustang II suspension, it’s just something we have experienced. Because the K772 is not meant to be loaded in tension, it can be “sticky” and not let your steering wheel return to center properly.

All of our Mustang II based control arms feature the K719 on the lower, and we machine the spindles to fit. If this seems like an upgrade you would like to make, give us a call and we can take care of you.

Quick hits from around the shop

1955-1959 GM Dakota kits very soon. AND MORE!

Been working on the design for the newest kit to our line. The 1955-1959 GM Truck Dakota kit. We will have this ready by the end of September in two forms. Our standard kit that accepts the stock ’87-’96 Dodge Dakota componentry and this will be our first venture into a tube control arm and coil over front end! Yes, you read that right we are going to offer tube control arms very soon. I have been working on the design and the fixturing to get these to a reasonable cost. So look for an official release of the newest kits very soon.

We have also been working on engine mounts and bolt on anti-roll bar mounts. I have some almost ready to go for Ford and Chevy engines in the 35-56 F100 kits. I need to check fitment on the others before we release them.

 

 

New information regarding springs and brakes

I do my best to keep up with information on all of our products. I was recently informed that the earlier 1973-1982 Dodge D series rotors for the 3000 pound front axle take a different bearing and are not compatible with the Dakota spindles. I made a quick note on the D-series caliper bracket selection about this change and will soon update all of the information to reflect the correct interchanges.

This morning however, was a question about springs for the Dakota IFS kits with 302 Fords. This is a work in progress and as I gather more information about the spring selections I will add it to the list to help you guys get the most out of your front end. This new information about the spring selection is in the Dakota Tech section.

LA Roadster Show 2015, We Were There!

What a show. The heat had to be a factor in the low turn out. That and the guys that go in first roped off over 90% of the spaces, leaving many swappers to turn around and go home. I spoke to two guys that demanded their $70.00 back because there were no available spaces. Even on Saturday a large percentage of the “saved” spaces were still empty with yellow tape and cones and maybe a lawn chair and a small pile of scrap metal to guard the space. I cannot see this happening for much longer before they the LA Roadster guys start having to do assigned spaces or at least check that the guys that paid for one spot only have one spot and so forth.

We set up with Hotrod Ron and had a good selection of stuff. The reception to our new fully bolt together ’32 frame was encouraging. The SBC engine saddle was the hit of the show! Now I’m going to have to put them into the store. Look for those items in the near future, but if you’re impatient you can always give me a call.

IMG_20150619_135942We talked with several satisfied customers and even saw Tim Thompson and his wonderful ’32 3W with the first mail ordered Full-X member installed. Of course Dr Marvelus and I had to take the opportunity for a shot of us all together. 2015-06-19 13.55.22

It’s summer time and we are still at it. More new products are on the way.
