My Bungee Fix

Going down rough road really bounces my drag link around and can be felt big time sitting in the drivers seat. I know this is old news and been talked about a lot. I have never seen any pictures of the fix so I thought I would post some. I hope my implementation was Engineer Mikes intent. I used two 21 inch bungees.

Rick, thanks for the pics. Have read about this fix but was not sure where to position the bungees. The clunking on my unit was reduced substantially with a good greasing, but not enough for my liking.

TIP for the day--the reason the question was asked about grease cups is that the "bungee fix" only treats the symptom. The root cause is the off-center design of the drag link. If you let the grease cups go unattended--you will eventually lose the end joints on the drag link. Havent found a commercial source for new cups--currently using a strip of rubber and a hose clamp--not very pretty but with plenty of grease--effective.

See if any of these fit: let us know, as I suspect many will need the same PN:

Brett--The challenge here is trying to find a generic cup that fits mine/your drag link ends -- you need to find cups with an approx. 1 inch small end, a 2.25 inch large end [but still wont fit the press-on design of the OEM end joint], and a width/thinkness of approx .75 inches. Besides the dimmension issues, you then have to pop/pull both end joints to install--alot of work to replace grease cups--IMHO....dean

Dean,

I totally agree. My solution is to grease them frequently and not particularly worry about the boots. Did that with bad boots on our 1993 coach-- joints still tight 100,000 miles later. Probably would not work up north with salt on the road.

I realize the boot problem. It's on the "take care of it list" but it's a long list.

Yes. The Pitman arm attaches to the steering box.

The drag link goes from the Pitman arm to the left steering knuckle on some coaches, through a bell crank on others (Freightliner and Chevy P chassis for example).

It runs front to back and can be easily seen by looking under the coach just forward of the left front tire.

Wondering if someone could elucidate the 'drag link bungee fix' issue for me?

I did a search on 'draglink', 'drag link', 'bungee fix', and see references to the 'bungee fix', but I still don't know what the symptoms are! (I believe it corrects a misalignment?)

I've had 'rattling' (or continual clunk) that seems to emanate from the left front wheel area since we've owned the coach. Could it be the drag link issue?

Thanks!

Rick- that looks great. Only addition I'd advise is to zip-tie the hooks to the running leg of the bungee.

Mark- your rig has the earlier small diameter drag link w/a smaller kink in it and less steering angle. Later coaches have a heavier link, larger diameter, and heavier so the angle makes the center of gravity place a torque on the link & it rotates & pinches the grease boots eventually damaging the ball joints. Your coach may be immune to this problem.

YUP--I was thinking this grease cup thing was only a problem for later model Alpines with the increased steer angle [ie, more bend in drag link] but its not. My 03 with 150K has the same issue with the cups--joints are fine. Pending a source for buying cups, have resorted to rubber strips, hose clamps, and lot of grease......
PS--a 3/4 inch piece of 1" radiator/heater hose fit on the stud from the joint to help fill the open area between pitman arm and drag link end--not pretty but effective....
