Exclamation Steering woes....

How necessary is power steering in a cobra?

Well this is 2 1/2 years and two power steering racks/pumps/pulleys, professional evaluations and R&R etc. later and I still have problems with leakage from my power steering system. I put the toy back up on jacks to inspect the source and it seems it may be another bad seal...? Well we wanna drive it so I'll git 'er done somehow but I'm wondering...could I just go with a straight mechanical steering system?

Sure I've got 265 front tires and the car weighs about 2800-2900# but could I get away with a straight rack and pinion manual steering and forget about pressures, lines, leaks, pumps, pulleys and belts for steering? Smaller tires on the front wouldn't hurt any I bet, when it comes to manual steering too, I'd be easy on that change.

Thanks for your feedback!

P.S. I put this toy together with all the automotive know-how of a 3rd grader so 'splain it simpul pullleez

Here it is simple: I have manual steering and it sucks.

It really depends on what you are using your car for. Regular street use, auto-X or ?.
Mine is a street car. I have manual steering and it works great. Just get it started rolling before you turn the wheel.

I want power steering, but would go with the electric version if I did it. I think it runs about $1,000? I don't want to spend the money now, but it is definitely on my list of possible things to change on my Cobra.

I have a manual rack, 33,000 miles no problem.
Cobra weights 2660 with me and a tank of gas with 235 front tires.
And a 15" steering wheel.

With a big block, 2900# and big tires, having had the power steering you would dislike it without it. Just put or get a new seal installed and enjoy it.

Default Tellin' it like it is...

Gracias for the input guys! I'll get her fixed up but then if it happens again I'll be willing to try out the manual steering with smaller front tires just to see if it's a reasonable worry-free alternative.

Check all surfaces for nicks.

Manual steering is fine once the car is rolling. Much better road feedback.

Dirk,
My Cobra has Corvette suspension including power steering that makes if very easy to steer. My 1963 Corvette (3,150 lbs) has the stock manual steering it came with. Back in 1963 they used bias ply tires that had a very small contact patch compared with the modern radial tires I now have mounted. The new tires are much better than the old, but the added contact makes the car difficult to steer until you start rolling. My bottom line is the same as several previous people - manual steering is a chore for things like parallel parking, but it's fine once the wheels start rolling.

My car has 255/50/15 on the front and it is a pain to steer. I would assume there are a lot of variables though to answer this question correctly. It depends on the ratio you want, the weight bias of your car, and how stick are your tires. Also, do you work out or not? LOL

My car is somewhere around 55 rear/45 front, so the front is light. I'm sure it would be a whole lot harder to steer if I had a heavy engine and a front heavy weight bias with big tires.

Doc, my kellison (basically the same car) has the same tire sizes and manual steering........don't do it......the rack seals are blowing out for a reason...
is the pressure correct with the saginaw pump?
have you shopped for a higher quality rack?

I agree ,you should not be having the problems that you are . Millions of cars have power steering without leaks
