rain or snow all over the road it sways and have to pull over or might go off the road
Not sure why you thought to post this because if it does not do that on dry roads then you don’t likely have a vehicle problem. This sounds like you need new tires .
Your first thing to do is have a tire shop look at your tires . Even if they show thread and they are the original tires then age has made them lose their traction .
Or maybe you need to SLOW down.
Seems reasonable. I certainly do that when there’s “rain or snow all over the road.”
Take it to an alignment shop to check alignment and tires.
Yep, check the tires for wear, and uneven wear. Get the alignment checked and adjusted, and get new tires, if needed.
Even if everything checks out OK, it could still be the tires, some are poor in the rain and terrible in snow. What is the make and model of tire?
One other free thing to check - the tire inflation. Are they inflated to the pressure on the car’s door sticker, measured before driving that day? Overinflation could make for poor handling.
When buying new tires, I always check the tirerack.com site and the November Consumer Reports for actual data on tire performance. Where I live, good performance on snow and ice is important, so if I am buying all-season tires I choose some that do well in those conditions.
All tire designs include compromises, so choose tires that do well in the criteria that matter to you. It’s a way to fine tune the performance of your vehicle.
also check to see if the sway bar links are worn out or broken. its a common part that I have changed on multiple vehicles. they are cheap and fairly easy to change.
1 car with issues? Is it car or driver?
My 2002 Outback came from the factory with Bridgestone RE-92 tires, and as I found out to my dismay during the first snow storm, those tires had so little snow traction that they constituted a hazard, IMHO. Because there is no industry standard for “all season”, a manufacturer can put those words on their tires even if it is not accurate.
I am nor sure the driver is to blame, I have had both cars and trucks that handled poorly in the rain and snow but seemed to have no problem in the rain. One was a 72 Impala, it had a swaying problem that magnified in bad weather. I blamed it on the rear suspension of coil springs and no radius rods to locate the rear axle. he trucks were GMC Brigadeers, They had a tendency to come from the factory with bolt holes in the frame that were drilled inaccuratly for the spring perches making them dogtrack down the road. You could hold them straight on a dry road but when it was slick you could hold it straight for a little while and then when the tire slipped it would snap you in a different direction.
I would check for the rear wheels not pointing in the same direction as the front. If you did not buy this new, it may have ben in a collision.
