Well, about 2 hrs into spindles and chill (with a dinner break) we’re basically at the same place. Lower balljoints WILL NOT let go. They’re frozen in the spindle and I don’t have a BFH or a pickle fork

Prob not member here, but I really like this guys tap into the oil cooler line on all his chevy's...makes things easier on trans flush day



I am leery of using those compression fittings on my truck. Not like it's super high pressure, but still....
I have done mine VERY similar. When I flush mine, I actually replace the filter and pan gasket first. Then I unhook the trans line from the radiator and connect a clear tube to it and run it to a bucket like this guy did, and then flush out the remaining fluid still in the torque converter and lines.

Ran into the same problem. This is what I did since the spindle gets replaced anyway and I was doing the lower ball joints as well. I took the spindle and the lower control arm off together. Laid them out on the ground so the ball joint stud is sticking up, heated the spindle right around the balljoint with a regular propane torch, sprayed the balljoint shaft with liquid freeze and immediately starting hitting the balljoint stud with a 2.5lb hammer. Couple hits it comes a part, lower control arm suffered no damage. However one would never let go, I had to cut the balljoint stud in half to separate the two pieces and pressed the left overs out of the lower control arm with a rental ball joint tool from the local auto parts store and left the stuck piece in the factory spindle. I had the ball joint tool rented since I had planned on replacing them anyway. I tried pressing the balljoint out of the spindle with a shop press and they wouldn’t let go, it bent the plate in the press that the piece sits on.

Hope you have better luck, it was a huge pain in the ass. But they will come out one way or another.

Yeah was a massive pain, it’s one reason my rebuild took so long, we spent the better part of a night fighting that. Tried multiple different sized pickle forks, tried just heat, tried the shop press, then went to sleep got up the next day and did the heat and freeze and cut.

I know Zach has plenty of experience so he might have already gotten them out, just wanted to share the info for others and incase he is still fighting them.
