Intermediate Steering Shaft
Tip
?€¢
If necessary, scribe location marks between the intermediate steering shaft and the steering column and the intermediate steering shaft and the steering gear to mark their alignment before removing.

There are a couple of things that can cause vibration ie wheel balancing that might be wrong usually vibrates when driving at 100-120 km/hr,ball joints that a worn,wheel hubs bend,steering knuckle excessive play,steering rack excessive play,worn steering UJ,worn steering column....

worn universal joint or cv joint.

Well, first of all, the odds are the tilt section can be tightened back up without replacing anything. There are 3 bolts that get loose over time.
Second, if you really do need another column, any A body GM car built between 85 and 90 will work. That includes Pontiac 6000, Buick Century, and Olds Cutlass Cierra. The only real difference is the steering wheel which you would not have to change.

If Your steering wheel keeps turning as in a 360 degree circle that means the steering column has broken or came away from the steering rack they are usually connected by what you call steering ujs something on shaft from column to rack has broken away nothing to do with cv joints or brake fluid if it was belt related that has snapped the steering will still turn it will be just really heavy the pump just helps assist steering my money is on the steering column shaft

To Remove:

1. Before servicing the vehicle, refer to the precautions at the beginning of this section. NOTE: The wheels of the vehicle must be straight ahead and the steering column in the LOCK position before disconnecting the steering column or intermediate shaft from the steering gear. Failure to do so will cause the SIR coil assembly (clock spring) to become uncentered, which may cause damage to the assembly.
   
2. Lock the steering column by installing the J42640 into the underside of the steering column.
3. Raise and support the vehicle.
4. Remove the tires and wheels.
5. Remove the power steering gear heat shield.
6. Remove or disconnect the following: CAUTION
   Failure to disconnect the intermediate shaft from the rack and pinion stub shaft can result in damage to the steering gear and/or intermediate shaft. This damage can cause loss of steering control, which could result in personal injury.
   
• Intermediate shaft lower pinch bolt and coupling from gear
• Pressure and return pipes from the gear
• Electrical connector, if equipped
  Stabilizer shaft links at lower control arms
• Remove the left stabilizer shaft insulator.
• Rotate the stabilizer shaft to access steering gear bolts.
• The outer tie rod retaining nuts.
• Using J24319-B separate the outer tie rods from the steering knuckles.
• Rack and pinion attaching bolts
• Rack and pinion assembly through the left wheel opening.
7. Transfer the outer tie rods if replacing the power steering gear.

To Install:

1. Install or connect the following:
   • Rack and pinion assembly through the left wheel opening and tighten the bolts to 70 ft. lbs. (95 Nm)
   • Electrical connector, if equipped
     Pressure and return lines to the steering gear and tighten the fittings to 22 ft. lbs. (30 Nm)
   • Heat shield and bolts. Tighten the bolts to 7 ft. Lbs. (10 N)
   • Install the left stabilizer shaft insulator.
2. Install stabilizer shaft Links to lower control arms
3. Intermediate shaft to the steering gear and tighten the pinch bolt to 35 ft. lbs. (47 Nm)
4. Install the outer tie rods to the steering knuckles.
5. Install the outer tie rods retaining nuts. torque the nuts to 22ft.lbs(30 Nm) plus an additional 180 degrees.
6. Install the tires and wheels.
7. Lower the vehicle.
8. Remove the steering column anti rotation pin from the steering column.
9. Fill and bleed the power steering system.
10. Adjust the front toe.

I had this same problem on my 99 Jetta. There is a copper contact ring on the steering wheel and brushes on the steering column that allows electrical contact between the wheel and steering column for the horn. I found that there was a copper screw that had backed out and was shorting against the contact ring when I turned the wheel. You should be able to see it if you look at the gap between the wheel and column. I had to remove the steering wheel to get to the head of the screw so I could tighten it back down. In order to remove the steering wheel, you'll have to remove the airbag; something that I was nervous about. I did an online search for "how to remove airbag on Mk III Jetta" and came up with step-by-step instructions. The whole task took me about 1/2 an hour once I found out what I had to do.

check tyres for wear-wheel balance needed if visibly ok-have a wheel alignment after a tyre rotation-best even tyres to be put on fronts-they will carry out a safety check all suspension and steering before doing the wheel alignment

Here is an exploded view of the heating/air conditioning blower box. This contraption is located on the passengerside under the dash. I've changed heater cores on other cars but never worked on a caravan so not sure how difficult it'll be. You may need to remove a few cover panels to access this and the heater core #22 is located behind the distribution box #6 containing parts 7-18 and hopefully comes off as a unit. I wouldn't want to put it back together just looking at the pic. You may just need to remove the heater tube cover #4 to access the connections and slide out the core.....NAH couldn't be that simple!!! Hope this was of some help. Good luck.

if your vibration comes and goes with different speeds, most likely problem is balance in tires/wheels. a bent wheel often vibrates more with higher speeds. if the vibration is stong in the steering wheel, the problem is normally in the front end, if you feel in more in the seat or body of the car then look to the rear end.
