1960 sedan front suspension sag?
Posted by: jwilsman ()
Date: January 07, 2019 05:21PM

Hi guys, I recently picked up a 1960 sedan in great shape. I've only driven it twice since I've had it so I'm still learn about the quirks of the car. Anyway, the front end sounds horrible so I crawled underneath to take a quick look and found there was some major abrasion from the pitman arm rubbing on the steering linkage and also the idler arm rubbing on the linkage on the other end. I can lift the front end with my hand enough to get the clearance so there's no rubbing.
Am I looking at replacing the front coil springs? is there something else I should be looking at?
-Thanks

We need to see a pic of this! The Pitman and Idler arms are part of the steering linkage..


How low does it sit? IF raising the car helps... something is amiss.

The steering linkage should never hit anything no matter how low the car sits. It sounds like some really loose parts or something is put together wrong.

Car sits level, My other car is a 64 and sets lower in the rear. I wasn't sure if the 60 had something unique to it that made it set level.

Higher Quality Rear Springs were put on the 1960?
Mine is level also.

I’ve seen quite a few 1960 Corvairs with low front ends — far more than any other year of early-models. My guess is that as part of the refinements made in subsequent years that the front springs were redesigned. And the same probably applies to the rear springs as well. My ‘60 Monza had freightcar rear springs on it. It had so much positive camber that it made freeway entrance ramps quite thrilling!

Later early model cars used the 1960 springs. The 1960 rear springs GM part number 6257159 were used alternatively on the right side of 61-63 models for heavy duty applications (part 3796318 on the left) but only used on both sides in 1960 models. Convertibles used the 1960 spring on the left side and 3828552 on the right.

If "heavy-duty" refers to police or taxi applications (since it includes the '61 model year) I could maybe see that. But my '62 Spyder with factory "heavy-duty" suspension had negative camber, not way positive like my '60. And the Spyder definitely sat lower than the '60 did.

I'm just worried that there's more going on than sagging springs. Could something loose be a problem, but its on both sides of the steering linkage. Hmmmm, I'll take some pics and research more.

Spyder has 50 lbs of extra equipment and weighs the car down in the back. The 1960 727 curb weight is #2,350 or 225 lbs less than a 62 Spyder 927 (cw #2,525+50 lbs. = 2,575 Spyder package). That will sag those springs! From the literature it looks like 1960 working height was 7.45" at 1,575 lbs on both sides and the 1962 working height was specified at 7.45" but with 1,725 lbs on the left side spring and 1575 on the right side. So these cars should be the same height.

crossmember is likely rotted out, have a mechanic (a real mechanic) inspect it before driving it on public roads. Sounds dangerous to me.

I had crossmember on my mind, yikes. Can any EM crossmember swap in or is 60 specific.

The '64 crossmember (and the '62 and '63 with factory HD suspension) will have provisions for an anti-roll bar. Other than that they're all the same.

The Spyder front and springs were most definitely different than those used on the standard 1960-'63 Corvairs. They're shorter and stiffer. A stock '60 coupe sits higher than a HD equipped Spyder does --just compare them at any Corvair show. If you're still not convinced, take them both around the block They ride and handle totally differently. And my '60 Monza was not the same as my '63 Monza coupe is.

I installed 64 Spyder front springs in my 60 Monza and noted no height difference. There seems to be conception that the heavy duty springs lowered the car but I have not seen this. What lowers the cars is 185/70-13 tires.

Attached are images from the GM reference materials for 1960 and 1963.

According to the materials the 1963 F40 special suspension package working height was 6.24 inches in the front (coupe @750lbs and convertible @850lbs).

According to the materials the 1960 working height is 6.17 inches @815lbs. but is higher at curb weight.

The curb weight height given for 1960 is not provided for later springs.

What is interesting the 63 materials show the 1960 rear spring used in the rear of the 1963 cars on either side.

I found my front end problem. I finally had time to get under my 60 and compare the steering parts to my 64. It looks like the drag link is bent forward like someone might have used it to tow.
Other than the drag link should I be concerned about other steering parts?

Great!! As long as everything else doesn't have any slop after lubing... replace it and you'll be fine after an alignment.

Awesome. I'll check the other parts out. I noticed a comment in the Clarks catalog that if the drag link on the 60 looks different than the picture the catalog shows then don't order that part. Did the 60 have more than one style of drag links?
