Problems:

1. When I hit 70+ mph, the steering wheel goes crazy and shakes???

2. Is Steroids worth it (does it fix bump steering)

3. When I floor it to about 3,500-4,000 rpm the engine makes a loud I mean LOUD screaming or sqealing noise.

Please help me with the problems, I need to find a way to get rid of the bump steering.
Thanks,

Number 3 sounds like a loose belt. Check the tightness by pressing on the belts with your finger (with engine off ). It could also be an alternator or water pump bearing.

Number 1 could be suspension parts in need of replacement. A properly working factory suspension set-up can easily handle 100+ mph.

Number 2 - Sorry, can't help you there. I don't use steroids, and the Corvette doesn't have Steeroids either.

 

For #1 Lowvette is on the right track but you may want to check wheel/tire balance too. That can have a big effect.

#2 - I have read good things about Steeroids. Check in history, there have quite a few threads about it in the recent months. I am very seriously considering it for my '69. I think it reduces bump steer, but I not sure.

#3 - I'll go with Lowvette here too. Check those belts as well as the accessories that are driven by them.

Best of luck.

 

Thank you guys for your help though I really need some ones input on Steeroids.

If you have it then please leave some info. on whether or not it's worth 1,100.00 and if it correct's bump steering.

Thanks,

with the other checks why is bump steer on your mind?
is the rest of the car right ?

 

1. Bad shocks and out of balance tires - if the tires are old, you may not be able to balance them correctly.

2. There are a few threads out there discussing Steeriods.

3. I'd check the belts. Some belt dressing would quiet them up.

None of your problems have anything to do with bump steering...if you fix #1, you might not even notice any bump steer problem.

Good luck

 

Ok well the belts are not the problem.

Bump Steering: I live in the city. I hit rush hour traffic all the time, the road I travel on the most has a many rutts in the road and pot holes. I am afraid that one day the tire might fallow a rutt and take me into another car......

So I was wondering if Steeroids can fix the problem.

Thanks for the input,, but I still need help with them all.

I am awaiting the Z06 wheels and then put new tires on, then maybe it'll fix the 70+ mph problem.

ik...i have Steeroids and as most of the guys here know...i am a HUGE fan...
i dont think what you are descibing is "bump steer" (someone wanna jump in here and explain bump steer)...
HOWEVER...what you are describing...the wandering and darting, ESPECIALY when you hit a bump and you dont know which way its gonna go except that you know that it wont be straight! you come upon a rut in the road and your car wants to follow it...
Steeroids WILL MORE THAN LIKELY fix that...
that was my biggest problem and Steeroids made it drive like a brand new car...
as far as "shaking" etc...that sounds more like other front end problems that Steeroids will NOT fix...aka...ball joints etc...

where are Jim Shea and Gene when you need them!!??!!
they could tell you all you want to know about your front end!
as for Steeroids...its awesome and i will never own another C3 without it again...

 

Well, I certainly an NOT a certified engineer, but I did my own rack/pinion conversion about the time Steeroids was developing theirs...and can say it's WELL WORTH the effort, and I feel for the time and effort duplicating the thing aa grand or so is a fair price....snot easy figgering out all that crap, and the use of a new/rebuilt rack and all the brackets make things pass quickly BY COMPARO.....

having said that, check the lower ball joints...they need to be replaced with MOOG and NO OTHER, I have been recently with AZone McQuay /Norris..and NOT happy...

the tie rod ends are of course critical, but if you do steeroids they are new wit the kit....

gotta check out the rear end too...that thing is as much to steering the car as the front, and them's the facts....
if that rear has any alignment problems, loose bushings in the struts, bad yokes in the rear, bad universals, or any combo of the above, you got deep judzu there....

SO after all the bushings in front and ball joints are deemed ok, you have to see about the handling, if it's fine for you, well enough, but don't forget that power assist valveing on the drag link where the pittman arms goes in, and the assist cylinder itself on the whole thing, and of course the idler arm on the pass side....up and down is it's favorite failure mode there.....

NOW if everything is just perfect, and righty tighty, for the MOST part the stock steering is fine for bias and early TALL profile radial tires....but if you go to the lower profile, and larger rim size, the handling feedback from the road surfaces is too much for that older type steering setup....hense....STEERIODS.....

and that ain't even 1/2 the problems with the antequated front ends, as NORVAL, PETE, and TT/Marc and I have discussed.....
