My s70 glt seems to be riding rough when i'm going straight,
and when i turn to the left it vibrates even worse...but
when i turn right the vibration completely goes away!!!????


On another note, every morning when i go to work it's hard to
accelerate on the engine, it acts like it wants to die after i
get going off a stop light. but after about ten minutes it does very
well and i cant notice it anymore...also on my way home it doesnt
do it at all....????? any help is freakin awesome!!!!!!

 

The vibration sounds a lot like a failing wheel bearing.

The other issue... could be several things. Is the check engine light on? if so, get codes pulled, and post those here. Auto Zone or Advance can do this- just don't listen when they say that the codes "say "X" part is bad- codes don't tell you that.

 

How should i check to make sure that it's the bearing before i
buy one and replace it?

on another note...re
actually no, the check engine light is not on...just the ABS light. thats
what confuses me, once again, on my way home today it didn't do it
at all. and i know the engine was cold.....so why only in the morning???
SO WEIRD!!!! thanx a lot man.

 

To me the vibration sounds more like a possible worn ball joint or steering tie rod end. Bad wheel bearing will generally make noise but would have to be really bad before it causes vibration. I would get the front end ckd out asap; could be dangerous.

On the engine issue, will need a bit more background info; has it been tuned recently (old plugs, plug wires, fuel filter, etc.).

 

As for the vibration, I agree with GDog, likely to be bad tires or suspension parts.

 

Thanx guys i will checkout the tie rods and such today.


as far as the other, I recently pulled the plugs out, they look
brand new. i also changed the oil and filter and coolant.
it has a pretty big oil leak that for the life of me i cant find.
ive been under the car for over an hour and peering into
the engine from the top also. no clue. the air filter looks
new also. could it possibly be like a vacuum hose or something
like that?

 

I havent checked the fuel filter yet. how do you do that?

 

If it hasn't been changed in last 50K miles, then it's due.

If you don't know how long it's been, what i do is look at it; if the filter looks as old as the vehicle, then i change it. Or you could ck the fuel pressure with a gauge to see if you're actually loosing pressure.

 

Sweet, thanx a billion man. do you know exactly where it is?
