32 Update: Finding A Rattle

Over 40,000 miles or so, the 32 had developed a little clunkle (“clunk” + “rattle”) that was driving me batty. The severity of the rattle was not dependant on the size of the bump, or how fast I was driving, or any other variables that I could vary. I could make it happen by jumping on the front passenger side frame rail, but not the driver side frame rail.

I tried to check the most obvious culprits first;

  • Are any exhaust brackets broken?
  • Are the emergency brake cables thwapping on the floor?
  • Is something clunking around under the seat? I have a power outlet built in to the front of the seat, and a while ago I noticed that the wires were not secured to anything and would click on the floor sometimes.
  • Is the heater/ A/C unit secure? Are all the vents secure in the dash?
  • Does the noise happen whether the windows are up or down? Sometimes the glass can clunk side-to-side when it’s down, if the whiskers don’t hold the glass as tight as the upper channel. Also, check the power window motor – maybe it’s come loose?

Moving to the outside, I checked every bolt I could see. Sometimes a click can be caused by a bolt that’s binding and just releasing at a certain point, or the threads are sort of riding at the edge of a hole. I checked the radiator support rod brackets against the firewall, I checked the air cleaner, I checked the headlights… I checked all those things again. Ready for the spoiler? When I was grinding the boxing plate welds where the engine mounts meet the frame, I must have sneezed at one point and taken off more than necessary. There was a tiny spot where the vibrations of the engine travelling through the mounts to the frame had worked a stress crack, and going over a little bump or jumping on the frame rail would cause the boxing plate to flex just enough to create a little click… kind of like a mason jar lid.

I was able to go over the spot with the tig, and now I’m no longer canning! It’s nice to be able to focus on something other than that little clunkle.

What are some noises that you’ve discovered in your hot rod?

Sway bar used on Corvette IFS in 1942 Chevy pickup

Here are some pictures of the installation of a universal sway bar on a 1942 Chevy pickup. I installed it to the rear of the a arm because it gave me much more room. It was going to be very close to and possibly hitting on the tie rods for the rack and pinion steering. I was very pleased with the sway bar and the installation. I will and have recommended your products. Thanks so much,
Jim

1950 Plymouth Sway Bar

Well, I just learned something… had a message on the answering machine from a gentleman asking about a front sway bar for his bone stock 1950 Plymouth. I returned his call, telling him our kit would require quite a bit of fabrication on his car, and he told me that the station wagon of that year had a front sway bar and he had a line on one.

So I thought I’d pass it along… need a front sway bar for your ’50 Plymouth? Try a wagon.

Custom 8-3/4 Dodge rear end Panhard bracket

John was in to the shop the other day and asked if we had a bracket for his 8-3/4 Dodge rear end to mount the Panhard bar. We don’t have one specifically for it, and after going over some pictures he had, we brainstormed and came up with something like this:

He used two Versatabs to mount the bar and formed a plate to box them in and to hold the bolts.

Thanks for sending the pics, John!

What if my frame is too high for the rear four link frame bracket?

Occasionally, we'll be asked about a four link installation on a closer-to-stock-ride-height stance. We suggest adding a length of 2" x 4" tubing to the bottom of the frame rails where the four link frame bracket will mount, which will usually be enough to level the lower bar and make a happy four link.

Cold Flow

Getting the ’40 ready for the road again, we decided to change the bushings on the coilovers because they hadn’t been done (that we could remember). The first challenge was loosening the lower mounting bolt. It’s not that it wouldn’t turn; it had attached itself quite strongly to the inner tube, and the whole assembly would just spin and spin. We soaked it, we hammered it, we impacted it… nothing was going to break the love that this little 1/2-20 bolt had with the tube it had got to know so well. We gave up being civil and cut the bolt in two.

Once the bolt was free (but severed), we popped the bushings out and here’s the damage:

Over time (though it would probably be more accurate to speak of “miles”), the bushing had worked itself into the grooves in the Aldan coilovers which are there to give you the option of running spherical bearings instead of bushings. The grooves are for a C clip to hold the bearing in place. No harm done; we just replaced the bushings and will go for another xx,xxx miles. I’m not sure exactly how long these coilovers have been installed, but it’s probably in the 30 000 mile range or more.

Moral of the story: check your bushings. Cold flow happens.

Sway Bar Mounted on a Motorcycle

Let me explain.

Nevermind, let the pictures explain. When we say it’s a universal sway bar kit, Daniel took us up on that claim.

Dear Daniel…
Daniel, I’m guessing you spent at least an hour or more figuring all this out! I don’t know anything about bikes, but this is very impressive. Thanks for the pics, and for using Welder Series parts.
