360 pulls to the right under moderate acceleration

Based on your description I'd say you need an alignment.

 

ONLY when you accelerate? I dont think I have ever heard of that before? Cant help you sorry, but am very keen to know what the problem is now.

 

Are you running with pirelli tyres? If so, double check the rear tyre pressures, i've seen this caused a variation in pressures, 3 p.s.i difference is enough to cause it. It's really wierd, most noticeable from take-off under hard acceleration....

 

my understanding is the early 360's had frame breakage problems in the rear. Perhaps that is a possible cause. Search fchat for the thread where Brian posts a picture of it.

Eddie is right. Nine out of 10 times when this happens on a 360 it is due to tire pressure.

 

Mine did the exact same thing.

First, I fixed my tire pressure, corrected 96% of the problem.

Then a week later did the motor mounts and now its PERFECT. Not sure what the motor mounts did to help. Maybe the whole engine cradle was shifting so much that it turned the tires just a little.

Lowering and alignment next

 

When the engine/trans mounts are gone, the whole power train unit moves more than normal, this pulls on the driveshafts in an uneven manner and and causes the rear alignment to be "pulled" out of a straight track, it causes the car to steer with the rear wheels. Sounds odd, but it happens. But I would correct the tire pressures and check alighnment before checking the mounts.

 

same thing happened to me. left rear was 5 lbs under inflated and it was bad. had a very slow leak in tire. fixed the problem and brought up the air and all was good. tracks straight as an arrow.

 

Wow! You learn something new everyday.
