SUBJECT:
Repair of pulling condition during driving or acceleration
REFERENCE:
Service Bulletin 60-5500, TNN 60-09, VIDA
Description
There may be complaints about vehicles which pull during steady driving or during acceleration. If an alignment is performed as per VIDA, using the specifications in Service Bulletin 60-5500, and this does not resolve the complaint, you may use the diagnosis & repair flow chart shown above to try to remedy the condition.
This flow chart presumes that the front and rear suspension are in good condition, without worn bushings, connections, etc. Tires must be checked to verify that they have tread life remaining, and are not worn unevenly which can cause pulling. There must be no existing accident damage, and any previous accident damage must have been properly repaired to Volvo standards.
Note!
The use of any alignment equipment, whether retailer-owned or sublet, presumes that the equipment is in good working order and has been calibrated to the alignment equipment manufacturer's specifications within the last 12 months. Volvo Cars of North America ("Volvo") reserves the right to request evidence of such calibration. Repeat repairs due to use of non-calibrated equipment, or failure to provide calibration documentation upon request, may result in warranty claim denial by Volvo.

TEST DRIVE NOTES:
The test drive should be done as follows: Accelerate rapidly up to 50 mph, noting how the car behaves during acceleration. Then hold the car at 50 mph long enough to note how it behaves during steady driving.
Then place the transmission in neutral and let the car freewheel, carefully noting how the car behaves the instant you put the gear in neutral: do the side forces reduce or disappear, or are they the same?
Vehicles always have a tendency to veer towards the edge of a crowned road. This tendency will make the car pull towards the side when driving in the "normal" traffic lane. To verify if there is a fault in the car, drive it on a perfectly flat road, or on a road which is crowned in the other direction. This might best be accomplished on a multi-lane road which has road crowns in both the left lane (to the left) and right lane (to the right).
