How To Remove Rear Upper Control Arm Housing Bushings

Posted by Spohn Performance | 10/21/10 | Tagged 4. Technical Articles

We recently came across these videos on YouTube and thought we’d share them with everyone. We often get asked the “easiest way” to remove rear upper control arm rear end housing bushings from the rear end housing and these guys do an excellent job showing just that.

You’ll note that in these videos they are showing you how to do a 1964-1972 GM A-Body Chevelle, but the same exact technique would apply on your 1979-2004 Ford Mustang, 1978-1987 GM G-Body, 1978-1996 GM B-Body, etc.

The first video shows you a very easy way to remove the bushings from the rear end housing. The second video shows you how to install your new replacement bushings in to the rear end housing. Enjoy!

Spohn Performance’s G-Body tubular front a-arms are featured on RPM Media’s “Project Stress Relief”. RPM Media is a premier high performance magazine publisher in Canada.

Every car needs a good solid foundation, and anyone who knows G-bodies knows that there are certainly some faults with the design of their frame and some weak points that need to be addressed with either using a big horsepower motor, or even turning it into a hopping low rider.

We started by taking our Craigslist found $100.00 frame and having it sand blasted. Once we got our frame back, we started reinforcing all of the common spots like boxing in the frame and beefing up the rear control arm mounts. We then cut out the unused portions, welded in our new coilover mounts and started to smooth out the frame for its body matching Charcoal epoxy paint job……

Please check out for expanded coverage including more pictures of the project and more information on the build.

Yes, it’s been a little while since we last brought you an update on Project Grandpa, our 1982 Caprice whose longing to see 11’s and still be nimble enough to master the autocross track. Yes, our ambitions are high, and to be honest, saying Grandpa was a little weak in the knees would be like saying a Corvette is a little faster than the Prius – a huge understatement.

OK, we know what you’re thinking: Seriously, a ’82 wagon? We get it, but
Grandpa is going to be the ultimate sleeper, running 11’s and even
tackling the road course. Can we make this happen? Stay tuned to see.

This abused wagon was in desperate need of major surgery to repair the crumbled bones and joints that were the shocks, control arms, and pretty much every suspension part on this car. If we were going to be able to claim this car a success, this is where we really needed to shine.

But before jumping straight into mastering the air element, we needed to lay a strong foundation on which to operate around our fine tuned air bags. Here’s a quick recap on where we’ve beefed up Grandpa, all in the ongoing quest to install our mean 655hp Dart big block 509.

Big thanks go to Dart, JE pistons, Howards,K&N Filters, Harland Sharp,
Moroso, Mallory, COMP Cams, Quick Fuel Technologies, and Professional
Products for making this rat motor the perfect plant for our Project

Wait, a what? That’s right, we somehow convinced Dart to build us this wickedly potent 650-plus-horsepower powerplant for good ol’ Gramps. This monster rat started with a Dart Big M block, with a stout 4-inch-stroked Howards Pro Max crank, billet rods, SRP pistons, a COMP Xtreme Energy Hydraulic Roller cam, topped with a Dart single plane intake and a Quickfuel Q 850cfm carb. When dyno’ed, this big ol’ boy pumped out 655hp at the flywheel.

Our factory suspension just couldn’t possibly handle the torque and torsion
that we knew we were going to be throwing at it. That’s why we went to
Spohn Performance for some serious suspension upgrades.

Thanks to help from Spohn Suspension and Energy Suspension, Grandpa was outfitted with new rear control arms, front sway bar, and steering – plus we were able to completely rebuild the front control arms. We knew that our 509 was going to push our Caprice’s suspension to its limits, so new, stronger and lightweight control arms and sway bars were just what the doctor ordered.

Being able to get all that power produced by the Dart block to the
pavement would take the right rear, and that’s why we went to Currie Enterprises to build us the right 9-inch. Fitted with a Detroit Locker and 4.10 gears, we’re going to be pulling a whole lot of sheetmetal down the quarter mile.

Al Marlow Drag Radial Camaro

Al Marlow - 4.84 @ 150 MPH - 1.25 60' on a 275 Drag Radial

Is Al Marlow the fastest man on a 275 drag radial? We think he is!

On Friday October 8, 2010 at Maryland International Raceway Al Marlow laid down a blistering pass of 4.84 at 150 MPH.

The complete Spohn Performance suspension hanging under this beast had the 275 Hoosier drag radials digging out a 1.25 60′ time. How’s that for traction on a small tire?

Congratulations go out to Al Marlow and his crew for their fantastic 2010 season so far.

Al Marlow runs a complete Spohn Performance Suspension - do you?
