I replaced all of my rubber bushings (besides motor mounts, tranny mounts,etc) in my car except the front control arm bushings and the bushings that the UCA's connect to on the differential. Now my question is should I get the spherical bearing that goes on the differential or should I just leave it alone and save the frustration of install time? My rear control arms have spherical bushing so I feel like I half assed an area by not going with the spherical bushings. All of my suspension mods are in my sig.

So you have the stock UCA's, but installed a new poly bushing in them?

If so, yes go aftermarket UCA's with a spherical end, such as UPR Pro Series. You have reduced the bind of rear axle with LCA's and re-introduced it again with the poly UCA's, silly

I have the spherical UPR uca's, but the bushing in the diff is rubber. Ill post a link to the part I am referring to.

Ya, you should get them since you already bought the UPR UCAs. I would have recommended a Baseline setup, but you should be jsut fine with these.

Ya, I had stop frequenting the forums for awhile and before I left UPR was the stuff people were using. I come back and I hear about Baseline, Griggs, and Fays2. I guess I will have to wait until I get another mustang for their parts because there is no way in hell I'm buying the same parts again.lol

That bearing replaces the stock rubber ones found on your rear axle for the UCA's connection.

Are you asking if you need a spherical at BOTH ends? Maybe I don't quite understand the question?

Jazzer... confused

marcuslee842

Yes I guess I could have worded it better. Would there be in measurable benefit to install these or should I just leave the the stock bushing installed.

Jazzer The Cat

It won't hurt to run spherical at both ends, just be a little more noise is all. You will actually get a bit less slop overall on launches and such.

Alright! thanks Devon and Jazzer.

Just get rid of the UCA's and get Panhard or Watt's Link and a Torque Arm.
