Latest chapter in the (slow) progress of my 10th Anny
Hey guys -
This Saturday I burned the whole day doing the front A-arm bushings. I bought a full set of Prothane polyurethane bushings - REALLY nice stuff.
Following the creed that everything I'm bolting back onto the car has to look as new as possible and work great, I removed the old rubber bushings, thoroughly cleaned the A-arms, then installed the new bushings.
This is yet another case of having the right tool for the job makes life easier . It took me about a half hour to remove the internal bushing by using a torch, a socket, and a hammer. The external bushing was way easier - light it on fire with the torch, let it burn for about 15 minutes or so, cut the metal sleeve with an angle grinder, and pry off.
The a-arms were covered with rubbery undercoating from when the car was new. It's a shame to put undercoating on beautiful cast aluminum! I cleaned it off the old fashioned way - scraped some off with a knife, and scrubbed with Super Clean and a brass brush. Took a LONG time to clean each up.
You'll also notice I have the Racing Beat swaybar endlinks as well - they're mighty sharp lookin'. I've had them for some time - they do make a difference!
The Prothane kit also includes ball joint and tie rod end boots that are polyurethane, so you can see them in the shot as well.
Here's the finished pics -

Here's the bushing on fire . Note how cruddy the A-arm looked - yep, that's what they both started out as!

Tonight I should get a chance to do some more work - I'm starting in on the intake manifolds. They're getting ported, and the extra nipples I don't need are getting cut off and welded shut. No vacuum caps for me!
Stay tuned!

Didn't really get 'em SUPER high - hell, they're forged at a far higher temperature than that. I also wasn't torching the aluminum, just getting the rubber to light on fire.
It sure was fun to watch!

Yo,
Pyro!! *grin* Dale, I'm glad you're posting these pics...makes my obsessive-compulsive behavior with my GTUs seem...well.../normal/. *wink*
Good job man! You remind me of Seth and his CYM FC, he pretty much stripped everything and had them re-plated/re-painted. It's good the RX-7 community has folks like you who do things right in order to preserve the FC, especially a 10th AE. Cheers!

Do yourself a favor and hit the arms with some mothers mag wheel polish before you get them back in. They polish up really nice and it tends to keep them clean. BTW you neighbors must love you...

I heard you can use a dremel too in order to remove the bushings. My bushings have been siting on my desk for the past 4 months, I'll see what I can do no that you got me all pumped up!!

I would give yourself plenty of time to get the job done - if you rush, you can goof things up, like scoring the area where the new bushing will go, etc.

The car's really unimpressive right now - it's up on jackstands in the garage with minimal stuff in the engine bay, no front subframe, the dash is out....it's seriously in pieces. It's dirty as hell right now too .
I did some more engine work tonight - built a primary fuel rail, test fit my secondary fuel rail, ported the lower intake manifold, and probably some other stuff .
This weekend I plan on pulling the steering rack out (it's only attached by the tie rod ends right now) to give it a good cleaning and once-over. I also need to drain and drop the tranny - I'm replacing the output shaft seal and giving it a good cleaning and inspection. And, I should be doing some more work on the engine this weekend - I should be able to install the front cover, get some more stuff painted and assembled, etc.

Thats what I like to hear. Something easier to put in than take out.

IMHO, the Prothane kit is a better bang for the buck than Energy Suspension - you get more stuff in the kit and it's around $10 less. I paid around $80 or so for my kit.
As above, just do a search on the Internet to find places that carry the Prothane kit. I think the place I bought my kit from was Don's Sports Cars or something.

Whoops! I thought the Energy Suspension kit didn't include the ball joint/tie rod boots. Oh well!
The Prothane kit is still cheaper, though . And it even comes with a free hat - woohoo!

I went on the Summit site, and couldn't find the kit for an Rx7. It was either Chevy, Ford or Honda. They were all well over $100 too. Do you have to ask them to special order it? How much is it from them?
Is there a very noticable increase in feel and performance with these bushings? My stock ones are quite worn, but money is scarce these days.

Total with shipping: 93.53
Energy Suspension Kit W/shipping : 99.00
I personaly went with ES, Their website would lead you to believe they have decent quality control. Prothanes site doesn't delve into how they develop.produce their products. 5.47 isn't worth it to me personally. Plus the ES kit is available in black, for the "sleeper" appearance vs. the "golly gee whillicker's Wally, you have KEWL red bushings". Unless you need the red to coordinate with your Neon lights! LOL J/K Dale!

Prothane is also available in black. I got red since that goes with the color scheme on my car.
The bushings were well-made, came with good instructions and more than enough lubricant for installation.
