    My new Rear Sway Bar.

    Finally gave up waiting for someone to sell a rear sway bar for my 2002 Ody and decided to make my own.
    It makes the van feel far less front heavy and flatter in corners. All good but could be better.
    I decided to start with a smallish 11/16 dia. bar off of a Ford I already had on hand but think I'll go to a 1-1/8 dia bar for the same application.

    I think this is a first among street Odys. Well done, Aadvaark.

    I'd thought of doing this, but was worried about the thin sheet metal in the luggage well being able to handle the loads. Did you weld in a "beef up plate" of any sort, or just use big fender washers?

    Off-topic...what is your signature's "Aaardvark" reverse vent window mod?

    The rear well floor is stiffer then you might imagine because of the stiffening ridges and proximity to the vertical wall. Plus I did use large washers and plates on both sides of the sheet metal.
    I'm going to post a few more pics that may answer some questions and also show revisions to the end links for greater ground clearance. It still works great after going for a spin this morning.
    Now I'm not sure I want to drop $250 more into a much thicker bar. 1-1/8 may be over doing it. As long as the eye to eye distance is around 44.5 inches about any ifs front bar should work that is fairly flat.

    Got to look around under more cars and trucks. Ha!

    Gee thanks. Aardvaark blushes!
    Not my first "Ody forum first" however.
    I was the first one to discover our 2002 transmissions did indeed have a serviceable filter from the factory.
    Not sure it kept any from failing though. Mine is still going strong however.

    FYI. The old Lower bar 11/16 dia. is the one I used on the Ody rear. Middle bar is the one I replaced it with on the front of my 1963 Thunderbird. Front 1-1/8 Dia.
    The top bar 1 dia is the Thunderbird newly added rear bar.

    Aardvaark II Rear sway bar:
    Decided to try a 1.06 Dia. solid bar off of a 1998-2001 Ford Ranger Pickup 2WD front. It's about 5x as stiff as the first .688 Dia Thunderbird bar after adding the
    one inch arm extensions. 1.06 bar approx 585 lbs.inch of deflection vs. 108 lbs/in for the .688 bar. Using the http://www.auto-ware.com/calcs/swaybar.htm rate calculator. Good for comparing bars but not really terribly accurate for calculating exact rates of sway bars since it assumes a few too many things.

    All I can say is wow! What an improvement. The small bar helped allot but this 1.06 D bar really make the Ody feel much lighter on it's feet and turns in
    like right now. I even got the back end to begin to break loose on one particularly sharp right hand off camber corner that doubles back on itself a bit. Whee!
    Based on my past road racing and autocrossing experience, this is about as stiff of a RSB as mine needs for the street on street tires.
    Now my Ody needs a racing lap belt for the driver at least.

    Too bad Addco or somebody doesn't do a kit. The second gen Ody is pretty easy being all bolt on and looking at the rear lower control arms of the 3rd and 4th gen Odys I don't think
    they would be too difficult to come up with a sway bar mount end link mount for them either.

    Btw. I looked under a all new platform 2014 MDX this weekend and it had what looked like a 1-1/4 D tubular rear sway bar out back of the rear suspension much like the 2013 MDX old platform.
    Perhaps the 5th gen Ody will get the new platform and a rear sway bar finally???

    The AirLifts still work nicely on the later models. They, too, add instant turn-in response. Again, nice job!

    'Vark, you ARE the man! Forget all those guys with stickers plastered all over their Cavalier Z24's and Civic DX Sedans...you are a true tuner, trying out the different bar iterations to get a balanced platform.

    1.06 Dia. solid bar off of a 1998-2001 Ford Ranger Pickup 2WD front. Got it. Did you use the Ford Ranger bar mounts? Are they poly or just plain rubber?

    This gives me the courage to possibly give it a try after I do the other stuff that needs to get done on the front end (new struts, tie rod ends, strut top bearings, front anti-sway bar end links, LCA bushings). I have Pirelli Scorpion Verde 235/50-18's and the tires' dry grip greatly exceeds the suspension's capabilities, even with Monroe Sensa-Tracs (w/ helper springs) and AirLifts in the back.

    After much crawling on the ground under promising vehicles I bought the Ranger bar (Hollander interchange number 524-00310 solid version) off of ebay and it included the stock Ford bushings Poly in good condition and brackets for less the $50 delivered. I could have gotten one for $35 plus state tax about 30 miles away but decided to get it off of ebay since time wasn't an issue. Several were available. Everything else came from the Hardware Departments.

    If you do decide to try the rear bar e-mail me and I'll give you the dimensions of my fairly easy to make clamp on control arm brackets and any other info you want for the 1999-2004 Odys.

    Decided to fab up some washer plates for the well floor just to be safe although most of the force is torsional in the bar some is exerted onto the floor. Pic:

    Thanks. I never would have thought up a handy way to attach it to the control arm in the way you did it.

    I just noticed you have an Opel Manta. Haven't seen one of those in ages. Are you still driving it?

    Yes. At the end of the month I'm driving it to Springfield, Il for a get together with other Opel owners at the Rt66 car show. It's in pretty good all original shape with about 52K miles but
    is being prepped to be repainted over the winter just to freshen it up. We have a very active Opel owners community over at opelgt.com and get together often around the country.

    On my control arm mount. I designed machinery for the meat packing industry before retiring and still enjoy solving design problems and fabricating parts. Wanting to keep the sway bar design
    simple and easy to fabricate was my goal. Only used my Sawzall, bench vise, small drill press and bench grinder in my garage to make the parts from hardware store steel.
    The 15 degree bend in the lower control arm plates for better link alignment wasn't really necessary but since I have a 20 ton hydraulic press I did it.

    Short one year report.
    My rear bar has been on for over one year and about 10K miles and so far everything is great. At this point I wouldn't change a thing.
