Wow very nice, I can't wait for mine to be done.

Another installment of this thread.

This time, it's the SPL Midlink Bushings. These are the ones that replace the bushings at the adjustment point on the lower arm that has the spring bucket.

1st pic is the bushing i'm replacing.

2nd pic of the lower arm.

3rd pic is the arm off. to remove the arm. Place jack under the spring bucket of the arm and apply some pressure. Not much.Remove the bolt at the knuckle first. Lower jack down and remove the spring. Next remove the adjusting bolt. Remove arm.

1st pic is the new SPL bushing and the stock bushings.

2nd and 3rd pic's. Using a 1 1/4" hole saw. Cut out the middle of the stock bushing.

4th and 5th pic's. Use a hack saw blade to cut 2 relive cuts in the shell of the stock bushing. Be CAREFUL not to cut into the arm itself. Not a good idea.

6th pic. I used a small chisel and hammer to remove the remains of the stock bushing. After this. Use a round file to remove any burrs around the hole and in it.

Here is where is install goes south in a hurry. This is the first time I have run into this issue with SPL parts. I measured the diameter of the bushings. Both at 1.492". Then I measured the ID of the holes in the arms. 1.421" for both.

That's 0.071" differences.

Should have anywhere from 0.001" to 0,003" difference. So now I have to call SPL on Monday and tell them. So that they can ship me new bushings with the proper OD's.

did you freeze them first? isni't that supposed to help shrink them prior to installation

Too much of a difference in the measurements. I had them in the freezer for 2 days, and even heated up the arm it' self. No luck. The bushings need to be machined to a smaller diameter.

Rusty · 02-02-2019, 07:07 PM

Oh, the instructions say to measure both the bushing and the hole. Confirm that the new bushing is between 0.001' to 0.003" (0.025mm to 0.76mm) larger than the bore on the arm. If this tolerance is out of spec. Please contact SPL for a replacement busshing.

All of the other bushings that I have replaced. All were within specs. Finally found one that isn't.

That big C-clamp is a ball joint press. That thing can handle a lot of pressure. It's done 6 sets of ball joints on 3/4 ton Ram 4x4's.
