renn911

Hi,
I recently purchased an 82 911 which was converted into a widebody by the previous owner. A few months after owning the steering wheel has developed a slight “shake” at speeds around and above 60mph. Also, periodically the car pulls to one side under braking.
My hope is that the front wheels only need balancing, but thought I’d ask if anyone has had a similar problem after a widebody conversion.
The car was aligned when I purchased it.

Thanks,
Walter

Sounds like a balancing issue to me.

As for the pulling under braking, assuming you have checked tire pressure...a few things come to mind:

1) poor alignment, meaning more toe out on the particular side that is pulls to.

2) faulty brake caliper or bad pads on one side, causing the other to "grab" more

3) BAD corner balance, torsion bar is off one notch or adjuster on that side is "askew"...if there is considerably less weight in that corner due to torsion bar mal-adjustment, etc. car will pull towards that side - think of a table with 4 legs and one is cut 2" shorter than the rest.

4) BROKEN torsion bar on that side...yup, it happens.

5) defective shock on that side.

Just my guesses, let us know what you find...

Jeff points out a lot of good things. Check the tires (balance and air).

Also, being in New England, make sure the roads are really flat. It's amazing to me how many roads are either really crowned or rutted. That will make your Porsche do some weird things. Let us know what you find....

In addition to that, a more subtle issue can occur if you have the original rubber brake hoses on. Over time, they can swell internally, which hampers the hydraulic effects in the brake system. The rubber brake hoses should be replaced around every 10+ years for best performance.

That said, Jeff provided a good list of things to look at. Shakes around 60 mph are usually wheel balancing-related.

Had this problem on my 911 - did all that is indicated above and it was still there. In the end dialed it to the tyres - the car was extremely sensitive to the tyre pressure, even 2 or 3 pounds was enough. My solution was to change tyres - problem gone!

good hunting.
