First answer was also my answer. Been there, dealt with that.

It's not the tire pressures. 33 PSI for all 4 tires. Lack of updates because I haven't had much time to tinker with the car recently. Worst case scenario I end up killing my tires.

I ended up replacing the diff mounts (left rear was torn) and the pulling got significantly better, but it's still there. My left rear tire was substantially more worn than the other 3 so I'm thinking I also may have an alignment issue or there's something up wrong with one of my tires (Federal 595 RS-RR). Gonna spend some time flipping them around this weekend before I take it in for an alignment.

Indeed. My 2001 was pulling to the right. Passenger rear tire was low. Back to 32 PSI like the other 3 and no more pull. It will be two years end of July that I've owned this amazing driving machine. This place is a ton of help and really good information.

Old thread, but that will cause it.

Rear tire psi, brand, age, and wear must be a match.

Definitely I had this happen with a difference of 10 psi and it was a huge effect. A couple years ago I had a slow leak in left tire and small difference would make it pull to one side.

[QUOTE=JamesD89;24376539]Nejde o tlak v pneumatikách. 33 PSI pro všechny 4 pneumatiky. Nedostatek aktualizací, protože jsem v poslední době neměl moc času šťourat v autě. V nejhorším případě skončím tím, že si zabiju pneumatiky.

Skončil jsem u výměny uchycení diffu (utrhl se levý zadní) a tahání se výrazně zlepšilo, ale pořád to tam je. Moje levá zadní pneumatika byla podstatně více opotřebovaná než ostatní 3, takže si myslím, že také mohu mít problém se zarovnáním nebo je něco špatně s jednou z mých pneumatik (Federal 595 RS-RR). Tento víkend strávím nějaký čas jejich převracením, než to vezmu k vyrovnání.[/QUOTE

Even a minor difference on rear tire diameter will confuse our diff, and cause pull one direction on gas, other direction off gas. Direction varies based on which side has smaller tire.

So anything that can cause tire diameter differences can cause this. Tire from different factories or date batch. Uneven tire wear left vs right. Or the most common, differences in air pressure. Even just a few psi.

Sorry, I misunderstood the topic.


My car goes out of the corner when going through a corner under throttle and when I take off the gas the car it closes back into the corner.
can it be understood like this?
I'm talking about street riding around 30-50 mph

Tires new 3000km squad 235/40r18, pressure 33psi, geometry set with 2-degree camber. No change

Thank guys
