New steering rack

My steering had been degrading for a while. It started out as sometimes hard to turn left. Like I could turn the wheel 35 degrees with a load on the front and the wheel would go to a manual feeling. If I turned harder, it would go normal and I could turn in more with power. After a while it started to become impossible to take any turn with speed without steering lockup. Then I got slow steering response immediately off center. Meaning, I could turn the steering wheel a little off center in either direction and it wouldn't steer the car much. It was loose.

I didn't diagnose properly and blamed the electric motor, so I swapped that out and the condition persisted. Before I even installed the motor, I knew it was probably not the cause. I just didn't pay much mind to the steering play until then. For the last couple of months, I have not enjoyed driving the car tremendously. Today, it has all been restored. The steering is perfect now. It drives straight as an arrow, too.

My diagnosis on the rack? Something wore out. For whatever reason, the driver side tie rod can move out of the rack without resistance from the pinion. I peeled back the boot and watched it. It was not the ball joint on the tie rod. I thought steering racks were a single bar running the length of the rack housing with threaded ends. Are the threaded ends of the rack rod fastened on somehow? How does the driver side move independently of the rest of the rack assembly?

Really easy job.

Are all the racks between the models the same? Ratio, etc? As in I wonder if there would be any advantage to using the ss/tc rack.

All racks are the same besides the 08-10 LNF. They have a different ratio and i believe are shorter than the rest.

The LNF does NOT have a different steering rack. The LNF knuckle steering arms are shorter however, which changes the effective steering ratio.

Thanks for clearing that up. I knew it was something with the ratio.

It definitely wasn't the ball joint. There was no play in that while the tie rod could move in and out of the rack.

Odd that you would choose this thread to ask about wheels for sale. You do realize that there is a classifieds forum, don't you?

I guess posting in a thread with a low reply count is better than not posting anything at all.

true, but it did bring me into the thread. Did you ever have loose feeling steering prior to replacing the rack?

I looked at the view count and was a bit surprised. So maybe there was some good strategy in his post selection.

For the steering rack, I replaced it after it had started feeling loose. It was the original rack and the problem developed slowly. It was hard to turn the wheel well before it was noticeably loose.

Could just be the tie rods in your case. When checking for play, I would slide the boot away from where the tie rod connects to the rack. That way you can see if the play is in the ball joint or coming from within the rack.

Well at least it will be easier to get to since I've already dropped the subframe before, unless you don't have to drop the subframe

No subframe drop needed. After disconnecting the column, disconnect the ends at the spindles, remove the 2 bolts that mount it to the subframe, and slide the rack out of the driver side wheel well. Very easy.

I might need to do this as well. Im replacing the intermediate shaft first and hope that fixes the sloppy on center feel and wandering on the highway.
