heading to the left!

heading to the left! - 03/28/12 10:51 PM

i've got a big issue with my 65 coronet. everytime i get on this thing in 1st gear it wants to pull to left, and i mean pull to the left! i steer into the pull and the car keeps drifting hard to the left. i literally tug on the wheel and the car won't even think about correcting. it's one voodoo child at WOT. i don't understand the problem at all. i've had this thing together for a few years and it's always been a leftie in 1st gear. now, this issue is with street tires but i've tried wide and skinny tires and the results are the same. i'm afraid to take this thing to test & tune because i don't won't an accident. i don't think the engine makes that much power, maybe 450-475hp. it has a stock street hemi suspension, car sits level, drives fine going down the road. anybody experience this?

stock 8 3/4 with a 3.23 posi. tried a 3.55 and the results are the same. i think i have a chassis issue and ain't smart enough to resolve it.

How is it cruising along at 40 to 60 mph with your foot of the gas ? Ron

From what your saying is this only happens when you
get on it... so I will assume it drives straight when
your just rolling down the road... I would look at
the rearend mounting... spring perches to see if the
rearend is moving

Yep I agree with Mr P. Sounds like soething is moving in the drivetrain when you nail it. Such as spring bushing or mounting bolts loose or missing. If its an auto you may see if you can get it on a drive on lift and then power brake it a little being real careful. That way you can be under the car just like it is on the road and maybe see something moving a bit when you power brake it. But again I stress be very careful if you do that. Ron

Better yet get a video phone/camera and have a buddy start it for you, pointed at the rear end and u bolts. Won't take long to figure out then. Check your spring perches to see if they have deformed or if the axle is moving on the spring.

If its steering that much I'm thinking the stud in
the spring is broke or gone that lines up in the spring
perch... and I would say its the left one thats broke

Id check also for a diff problem or tire size ( roll out ) or axle spline stripped

I'm not sure about this ... BUT maybe the posi is
taking a dump.. but I'm not sure if only one tire
would be slipping all the time..(I guessing that
when you changed gears you used the same posi)

the studs are all there, u-bolts torqued to spec. i had this thing apart a couple of weeks ago and everything looks secure. i'll try a re-inspection and try some measuring. thanks.

a buddy suggested getting someone to watch the back and front while doing a wot in 1st. thanks for the reply.

I'd have to agree with the rear, but I would also check the motor mounts, as I had one go bad on a my Challenger and when I would jump on it, it would pull hard left ? under normall driving it was fine??? I look at anything, just go over the car with a wrench and check everything look for anything that maybe moving. If its that bad you will see signs of it somewhere.

Also be sure to check the toe setting with the car jacked up a little in the front. If you had a tie rod starting to go it might start to steer the car when the front end comes up.
