Well front end alignment and tire problems are nothing to be taken lightly for sure. Hitting potholes will often affect the alignment of the front end which is more than likely responsible for the vehicle pulling to the right. The shaking can be caused by a number of things. There are little weights on the rims of car wheels. These are to correct any imperfections in the manufacture of the tire. Kinda like how you have to balance a ceiling fan because each blade doesn't weigh exactly the same. It's possible that hitting the pothole may have knocked off one of your weights and now your wheel is out of balance. And I can't say strongly enough that you need to have ALL of your lugnuts. My suggestion is to go to a tire store IMMEDIATELY. Tell them what you've told us and I'm sure you can have your tires balanced and wheels re-aligned for a resonable price.
you need to check the pressure in the tires when there cold,or not have been drove for a while the pressure will read more if the air in them is hot,it will vary about 3-5 pounds,but you might want to have it checked just to see if it busted anything in the front end of it,if its pulling bad it may have knocked it out of alignment,but have it checked to be sure,its better to be safe than sorry,good luck hope this helps.
I knew I heard that someplace else, nice copy and paste.
On the same note though, my 03 is getting rough as well, it certainly doesn't feel like anything is broken but I am contemplating replacing my shocks. The way to see if your shocks are good is to push down one corner of the car and see if it starts bouncing because it should only go down and up no more than twice. Any more means bad shock on that corner. Do this simple test and at least that might eliminate shocks as the cause or point to one.
I agree, if wheel balance was an issue you would feel vibration through the steering wheel at certain speeds whether you were hitting a bump or not, this definitely sounds suspension related for both tdot & junior.
I recently installed the FE4 V shocks/struts & eibach lowering springs, had 4-wheel alignment, plus I'm running lower profile 18" tires. As much as I love how the car sticks to the road, I've pretty much ruined any soft Cadillac ride. The WI roads are horrible from last winter and if I hit one of the many potholes it about knocks your teeth out. The worst thing is all of the heaving that has happened to the roads, especially at bridge decks. There's no way to avoid hitting it because it goes across the whole lane. Next time I get new tires I'm definitely going from a 45 to 50 sidewall to see if helps the ride at all.
I'm runing 245/45/18 (45/18's like you). You think 50 sidewall won't rub if you have 4 girls in the car and a few of their boyfriends in the trunk?
I've noticed there are quite a few people here from Toronto... I'm looking for a good mechanic, someone reliable who's as honest as you can get a mechanic to be these days, I guess... I'm willing to travel the GTA... if anyone has a shop they've had good experiences with that they could refer me to, it'd help a lot. Thanks.
Was this issue ever resolved? My '03 just started making a LOUD popping/clicking sound in the front end when going over even the smallest bumps/uneven surfaces!! I have the Eibach's and have had nothing but noise problems and I have been to three different shops who can not find anything wrong!! One thinks the strut is going out but wanted $400 to replace?
control arms loose
check all rubber bushings
upper/lower ball joints
try jacking the car up and grab the wheel and try 2 shake it a little and see if you can hear anything loose then try 2 pinpoint where it is comming from.
just suggustions on trubleshooting...hope it helps
