Replace Rack and Pinion Steering - really?!
After returning from the track last week, I had a vibration in the steering and felt it in the front wheels. I suspected that I had flat-spotted or cupped my street tires as I was running with maximum negative camber with unknown toe (corded my NT-01s on Saturday). I replaced both front tires, but the vibration/whop-whop was still there. I made sure it wasn't the rear wheels/tires even though it felt like the vibration was coming from the front.
The sound and vibration seemed to come from the right wheel and was pronounced when weighting the right side by turning left so suspected the wheel bearing was going bad. I took it into my local mechanic who reported the rack and pinion gears on the steering column had play and needed to be replaced - quoted parts alone at $1,800 with unknown labor. He said that the wheel bearings were fine. I asked why it felt like the vibration is coming from the wheel and why the steering feels solid and like it has no play, and he said vibrations coming through the wheel were due to the play in the pinion gear. BTW, I have 96,000 miles on the car with a new engine since 82,000. I'm taking into the dealership on Monday, but I wanted to get your advice or suggestions as this isn't making sense. Your feedback is appreciated. Last edited by dbyrd; 07-25-2014 at 11:00 AM.. |

The column has some joints that do wear, in the lower assembly.

I believe so, and it's time consuming from what I understand. Your problem doesn't seem to be related to this issue. When your engine is off, and you wiggle your steering wheel, is there a lot of play/noise?
Generally when folks have this replaced it's because of the play in these joints, but your issue stems from the wheel bearing or hub area, might even be an FCAB or thrust bushing that's out.

Definitely get the opinion from the dealer on this one. Sounds odd that the problem is as stated from this mechanic guy given the lack of play/noise when sitting.
Post up the results from the dealer. GL! |

I believe #s 14 and 19 in this diagram. These would be pretty rare as far as being problematic, at least folks on this board haven't made much mention of them. Wheel bearing sounds more reasonable, cheaper. If it's a wheel bearing, I would expect some play if you try to move the wheel around while fitted on the car.

i doubt you have a bad wheel bearing. It would have to be really shot to result in a vibration. I had a bad left front wheel bearing (fair amount of track use) and the symptom I had was a rumbling noise coming from the front end most noticeable at freeway speeds going around long sweeping right hand corners.

So true - you asked a question about steering problems and people are posting part diagrams and shit (hell yeah thekurgan). It's that kind of stuff that makes this place great!

The dealership says it's the wheel bearings and that both sides have noise. Apparently, they used a listening device. They want $1680 for both sides. This is much less costly than replacing the entire steering assembly, but seems like both sides wouldn't let go at the same time.
I have two other estimates from local shops at $1200 and $933. They both say the replacement is relatively simple so I'll probably go with the less expensive mechanic unless I hear otherwise from the forum. I'll keep this post updated - thanks for all the helpful feedback! |

Dealership came way down in price so I'm going with them. I'm still concerned that I have some wear to the steering assembly. I'll post an update when I get the car back.

I had no idea wheel bearings were so expensive.

Yeah, I just looked up the parts on realoem, I was thinking the bearing itself was separate. That price makes sense now. I hope this resolves the issue.

Got her back this afternoon and the problem is resolved - needed wheel bearings.
Thanks for all the advise - loved the diagrams and specs sheets.
