There is juddering coming from the front axle area after fitting the reconditioned rack and pinion st,?

Question

The engine is not missfiring at all,the juddering,rubbing sound is clear as i drive slowly.

Answer 1

Rack & pinion steering usually has a damper fitted to reduce free play check this first, also could be track rod ends not tightened correctly. May have nothing to do with steering and be a new fault with disc brakes out of true or pads worn.

Answer 2

The rubbing sound could be from your front brake back plate / disc if you can hear it at low speed.(as previously suggested) As for the juddering, it could be that you did not 'bleed' the power steering system (if fitted). Air lock & surge of fluid on operation of steering = 'thumping' or juddering thru steering wheel.Check you have replaced & torqued everything up correctly, including wheel nuts!!. If it was wheel balance, that would not usually show up until over approx 50 mph. Get it checked properly by a good mechanic, not some 'rip off' clutch & brake outfit!!

Answer 3

If you did not get a wheel alignment straight after fitting you should get one . check the tread on your tyres to see if the wear is even. otherwise check your tie rod ends,wheel bearings and the rack mounts to make sure all are tight

Answer 4

Hi

Did you have the wheel alignment checked out after fitting the rack?

Answer 5

the toe needs to be set at an alignment shop but you can get it close enough to drive it there with a tape measure
1. center steering wheel
2. loosen lock-nuts on both outer tie rod ends
3. sight a strait line beside drivers side tire parallel with lower rocker panel and mark beside driver side tire
4.now turn driver side inner rack end until tire is parallel with the line you just made
5.tighten down driver side outer tie rod lock nut.
6. using tape measure : at as close as you can get to 9 o clock position on tire inside edge measure ac cross to the inside edge of opposite tire and record reading.
7. now measure at as close as you can get to 3 o clock position once again inside edge to inside edge and record reading
8. turn passenger side inner rack end until readings become equal [slightly shorter reading at 9 o clock reading of 1/4 inch or 6mm is OK]
9. tighten down passenger side lock nut.
while this is not an accurate way of making this adjustment it will get you to the alignment shop without destroying your tires good luck and don't forget to set the park brake and block rear tires for safety before you get started on this procedure

Answer 6

did you fit the parts because it was doing it before if so you have replaced the wrong parts. should check stub axle and track rod ends and cv joints
