- While performing a prealignment inspection: Technician A says that improper front-wheel bearing adjustment may affect wheel alignment angles. Technician B says that worn ball joints affect only the camber angle. Who is correct? Technician A only Technician B only Both A and B Neither A nor Barrow_forwardWhile driving straight, a FWD car pulls to the right. The most likely cause is. more positive camber on the left front wheel compared to the right front wheel sagged front springs and improper front-wheel toe setting less positive caster on the right front wheel compared to the left front wheel the SAI on the right front wheel is 1*A degrees more than the SAI on the left.arrow_forwardwhat is the formula to measure gas from tire interior?arrow_forward
- Technician A says that replacement wheel rims should be the same as the original equipment wheels in load capacity, offset, width, diameter, and mounting configuration. Technician B says that if wheels are installed that have a different stock width or diameter, make sure to use a tire that has the same overall width as the original tires. Otherwise the vehicles wheel-speed sensors, speedometer, antiock brake system, and many other systems will be affected. Who is correct? a. Technician A only b. Technician B only c. Both A and B Neither A nor Barrow_forwardHow does a technician determine the proper inflation for a vehicle's tires?arrow_forwardWhich of the following statements about sidewall markings is correct? a. The load index is given as a letter. b. The traction and temperature ratings are based on the speed rating of the tire. c. The tires recommended inflation pressure and load are indicated. d. The DOT code indicates when and where the tire was made.arrow_forward
- When adjusting a vehicle to counter the effect of road crown, what is the adjustment would you make-Adjust the left front wheel with slightly less positive caster-Adjust the right front wheel with slightly less positive caster-Adjust the right front wheel with slightly more positive camber-Adjust both front wheels with slight toe-outarrow_forwardAll of the following statements are correct except?a. Tire inflation pressure directly affects traction.b. The recommended tire pressure for front andrear tires may be different.c. The recommended tire pressures are oftenlower than maximum pressures.d. The recommended tire pressure is moldedinto the sidewall of the tirearrow_forwardTrue False? Camshaft straightness is checked using V-blocks and a feeler gauge?arrow_forward
- Tech A says that negative caster provides directional stability. Tech B says that positive caster results from excessive positive camber. Who is correctarrow_forwardWhich of the following would NOT be cause for rejection when checking the tire condition? Any tire has a fabric break or cut exposing ply or cord or any tire is in contact with the body or frame. Any tire tread or recap is separated or any tire is flat. All of the statements shown are cause for rejection. Any tire has any bumps, bulges, or knots or is repaired with a boot or blowout patch.arrow_forwardWhy are the wires leading to some wheel-speed sen sors twisted?arrow_forward
