Weird Caster Value

[ericmaxman]

As a follow up

Quick question.

My car's alignment lari very fast. Last weekend has my alignment done at shop A, then drove to shop B to do my oil change. I noticed alignment wasn't that great, so I drove to shop C (Near my place) to redo the alignment.

Here's some of the things I found.

Shop A - Replaced rims, adjusted camber on passenger side to about -1.7°, while the driver side is -1.5°. Alignment was also done here.
Shop B - Some 50km away (Puchong), just did oil change, nothing more.
Shop C - Near my home, they checked my alignment and camber, and said camber lari, as the passenger side, camber lari till -2.7°, and toe lari some 8°. (Which explains why the steering needs to angle a lot baru can go straight). Shop C did my alignment, but I told them not to touch my camber

After driving off from Shop C, steering have to angle right a bit, as the car was pulling left (slightly). Was worse earlier.

So, what could be the cause? Different shops have different equipment, that I know. But such huge discrepancy from shop to shop? Camber bolt rosak? Worn bushings? Worn tie rods?

A bit more, went up and down Genting, alignment did not lari, just that it's rather annoying having the need to angle my steering to keep straight.

machine calibration!

Maybe, but the caster value? readings from another shop seems consistent.

Any accident involving the wheels?

Only potholes. Last major accident was 2 years ago. Kena engine, mostly.

Potholes usually camber and alignment will run. Very rare caster angle, as that is wheel forward / backward angle.

Kena one painful pothole near Ikea

does your steering sometime pulls left and rigt on uneven road?

long time ago i went throug a super hole on the road on my lowered suspension and stock 14inch rim plus michelin certis tire.
it was so nad that only a loud 'kung' is heard.check everything when reach home.and can see mark on the rim which shows the tire actually compressed till flat and leave mark on the rim.
both tire,rim,allignment survive the horror.

recent incident with the kenari oso was very2 lucky.
cant see the pot hole until the last minute but decided not to do hard braking and sudden swerve as my wife's sister is carrying her few month old baby as the back.this time 'kuk' sound.
tire,rim,allignment survice the mishap.the center cap does not though.

Rough road yet, uneven not so. Car pulls left now.

My ex Wira did not survive one big hole while coming back from outstation using Federal route. Front and back went thru' that hole, kluk, kluk, came back, next day send for alignment check, both left side that went in camber out....

try check your lower arm bushing....especially the main bushes...



if replaced still gave same reading i think your subframe/chassis actually lari a bit during accident involved the engine back then...

Funny because the problem happened right around the same time I hit that pothole.

After the accident things were relatively ok.

have a look at the steering rack bush.if u are on stock tire size and the bush are worn out then it might solve the steering wondering issu and allignment issue.

the weird caster thing,i dunno.maybe some bush are damage during the impact.hard to check without making tedious inspection on each link.
for the chassis to lari a bit is hard as if the impact happen on the tire,there are lots of bush and link that will absorb the impsct first.unless the impact is so hsrd on the engine as it pulls on tye mounting soo hard that slight movement is caused.

My steering rack bush already replaced with PU ones.

I got my mech friend to check out, he said its fine

 

[gunnerzz]

not sure abt pu but i amnon stock rubber replacement and i put a piece of timing belt.between the bust and bracket to make it a bit tighter and last longer.

Interesting fix.... How well does it hold up?

Timing belt quite thick right? can go in. I did for my old car last time, but I add the lorry tube instead. Cut into shape and wrap it in. Lasted until I sold the car......

My ex colleague did have an accident. Not major but he hit a lorry wheel which was on the road. The impact damaged his bumper and left wheel. After repair he mentioned the car pulls to the left and send to many shop do alignment also cannot solve. Finally found out his caster angle out so cannot do anything....

Caster angle lari, no fix meh? If replace lower control arm?

Yea, I am interested to know as well. Mine seems to be camber only since I see my left is negative and right seems straight lol

last time if change to normal aftermarket only last 6 month with crazy cornering and high speed on uneven road.with the timing belt on,abt 2 yrs with same style.
if normal driving i bet will be 5 yrs above.
i am saying 2 yrs because i can feel movement at high speed.by high i men 130-140kmh on uneven b-road.on normal driving will feel normal.

since last time my back is in great shape i replaced it.the rubber one is dirt cheap.now got movement again as forgot to swap the bush when channging the rack.dpnt bother to change as didnt drive it as much and if i do,no longer ballistic until some type-r wannabe think he can outrun my uncle car at a traffic light.was feeling too much freeplay.

if u van see it by eye then its bad already lh bro..
r u looking for a cheap reason to upgrade yr tire by saying edge already botak???

does a laser chassis allignmet rig available in Malaysia?
i can only see this as the way to fix it.

Camber can adjust, easier than caster

Not only your lower arm. it is right up to your absorber mounting at the top. Lower arm comes from inside means left to right. Caster angle is front to back

Absober about a year old plus a bit only. Adoi

 

[gunnerzz]

ah yes,if u r lucky then might be the absorber rod is bent

"Lucky"

If not, then lower arm. Hmm
