When I accel, pulls to the right?
 
I did a search and the forum search doesn't like the word "Right" didnt know how else to ask hehe..


When Im coasting or just maintaining speed it drives straight. If I get on it and accelerate fast it will pull slightly to the right enough that I have to continually counter steer left (very slightly approx 1-2 degree in turning), then when i let off i have to correct by turning (slightly) to the right again. Any ideas?

there was a thread about this a couple of months ago..... search for "bump steer"

it could be a alignment problem?

Thanks TurBRO240

In my new search I found this which I think applies in my situation....

So I guess I need to inspect these bushings, whats the easiest way to look at them and what is Spherical fittings?

in order of most probable

low right rear air pressure.

too high left front air pressure. (run 30 fr 28 rear set cold)

check right rear shock for hydraulic failure... (fluid on outer shock body)

check left front shock for hydraulic failure.

check static ride height equal left and right rear


there could be other possibilities IF the car doesn't drive straight or roll straight at neutral throttle. (they would be suspension settings and bushing/bearing slop)

keep us posted,

howards on the money. Check tire pressures. My car kept doing this, i had a slow puncture.

Bent front swaybar mounts. It preloads the bar and makes the car pull different directions when the nose pulls up under acceleration.

Check the obvious stuff first: air pressure, alignment, etc

Do you have all the same brand tires on all four of your wheels?

My car does the same thing. The back always goes right when the tires break loose.

KaiFD3S 04-26-07 02:46 PM

check the diff bushings...

My car was pulling to the left, especially while braking. It wasn't pulling very hard, and I think the problem developed slowly: someone else noticed it when I let them drive the car. They attributed the problem to unevenly worn brakes.

When changing coolant, I eventually found a bent left swaybar mount. After replacing the mounts (Mazdaspeed), endlinks (Mazdatrix) and swaybar (Racing Beat), the car tracked straight again.

My car did this when I put 2 different tires on the rear, Michelin MXX3 and Michelin Pilot SX (almost identical tires). When I changed to my stock tires the problem was solved.

hanman 04-26-07 07:16 PM

I had the same problems with mine, two different brands of tires. When I put Avon's all around the problem went away.

Yep tire pressure's will sure cause this. That's assuming that your running the same brand and size on the rear axle. If your running a different size or brand on either of the tires on the rear axle buy new tires.

I'd suspect tire pressure before this fix.

my mr2 used to do that and this beat up truck i had.... changed the SHOCKs and that was is!!!.... maybe ur shocks are blown... check them how long u had them? miles on them?

+1 for the diff bushings. My car did the same thing under acceleration. Worn diff bushings will cause the rear end to torque out of alignment under acceleration. You don't notice much under cruise (which is why your car will drive straight) cause the rear end doesn't have much load.

gary28482 02-04-09 06:07 PM

hey guys sorry to bump this tread up my car is doing the same thing of pulling to the right and i have found out my rear left shock is blown could this be the problem

BigJim 08-12-09 01:39 PM

pretty sure that even if its not the problem, its a damn good spot to start...
