Adjustable rear control arms.

[mang213]

Well, they come pre-lubed, but that worthless gunk washed out within a month. So I used the synthetic mobil 1 red grease, which isn't silicone from what I can tell, but it is synthetic. The bushings have actually broken in half on my rear lower control arm. I ordered a bunch of new ones from Spohn and am going to modify the bushings a bit to see if I can get some grease channels burned into the surface of the bushings. We'll see what happens, and I'll post my results

I don't know if this helps but I am using the Spohn adjustable rear panhard/track bar with the del sphere joints and I have been happy with them. Been running it for about 6 months, just make sure to tighten the joint down really good before installing it, other than that the Spohn product is amongst the highest quality parts I've laid my hands on. The packaging and the build of the part itself confidence inspiring. I will probably get their rear control arms soon to adjust the ujoint angle, I think I am getting some driveline vibrations.

How will you add grease channels?
Quality is definitely good and packing was a pain in the ass took forever to cut it all off lol I still gotta install and see how they do on the burb. Been so busy lately it's insane. Burb goes for anual undercoating Saturday so hoping to get rear done before than otherwise it will be a mess

I plan on taking either a soldering iron or some 12 to 14 gage wire and get it really hot and burn really small grease channels into the surface of the poly bushing to make sure the grease can spread out thoroughly. I have the Spohn panhard bar and the boxed rear lower control arms on my Tahoe. They look good, but I have never been happy with the noise from those bushings. And the rear suspension binds up a lot because of those damn bushings, so I'm going to experiment with my grease channel idea and see what happens

Here's the broken poly bushings on the Spohn boxed rear non adjustable control arms. Still waiting on the new bushings to arrive to do my grease channel test. I didn't bother checking the panhard bar bushings because I had seen enough carnage and disappointment in one day for these less than two years old bushings

Well, the grease channel experiment for the Spohn bushings is basically a no go as they already come with grease channels. Not sure if the original bushings have these same channels but I'll post pics after I do the swap. I've attached a pic of the new bushings for reference

Hopefully those last longer than original bushings did

Yeah, can't get any worse than the old ones.

These bushings were absolutely trashed and they've only been on my truck for about a year and a half. I'm not blaming Spohn at this point currently, but if these new bushings let go then I'm going to have a serious problem with them. Pics for reference. The carnage is impressive

And yes, the original bushings did have the same grease channels as the new ones
