steering problem

[lloydwena]

hi guys! ask ko lang kayo kung bakit, pag pinipihit/kinakabig ko yung kotse ko pakaliwa o pakanan, di ba dapat babalik o iikot siya pabalik? yung sa akin. hindi na umiikot pabalik, kailangan mo pang alalayan..
ano kaya ang possibleng sakit ng oto ko? magkano kaya aabutin nito? at saan ang ok na pagawaan para dito?

salamat sa lahat ng mag rereply.

=)

lloydwens,
the info pertaining the vehicle is incomplete if not missing. the steering factor that brings the front wheels back to straight ahead position when the steering wheel is released while the vehicle is in motion is called king pin inclination or steering axis inclination. it is the tilt of the imaginary line between your upper and lower ball joints for double wishbone independent front suspension and for solid axle front suspension, the imaginary line between the upper and lower knuckle bearing, for mcpherson strut suspension will be the imaginary line between the balljoint and the strut mount on top where the strut attaches to the body structure. this tilt is built in to the suspension to keep the wheels straight ahead when in motion. this imaginary line is tilted inwards on the top. if the suspension has been modified, altered, damaged from collision, the returnability of the frownt wheels is gone. or if some of the steering components have been replaced and installed too tight (binding), it will not return by itself towards the straight ahead direction. or in some cases, there is a steering memory on the worn parts of the balljoint, strut mount bearings or the knuckle berings. if you had parts of the car arc welded and the grounding cable was installed far and the steering components are in between, the knuckle bearing or ball joints on some will get brinelled making a gouge or ridge where the steering will rest at its lowest point. identify your vehicle completely and what has been done to it to pinpoint possible causes and remedies. read up on what important info are needed to post.

^ What Jick is trying to say is that, normally, the steering geometry is designed for positive caster for straight-line stability. Modifying the suspension, as well as wrong camber and toe settings would sometimes mess up the positive caster that it cancels its effect of self-straightening. It's best to have it looked at by a qualified suspension techie.

yep, the caster angle is responsible for maintaining the straight-line stability assuming the camber and toe settings are within range. to offset the roadcrown or the arch of the road surface when viewed crosswise, the camber is set more positive on the port side(driver side) or the caster is more positive on the starboard side (pax side). the S.A.I=K.P.I. or the steering axis inclination is equal and similar to king pin inclination and is responsible for returnability to straight ahead from a turn when the vehicle is in motion
