Hi - I recently got a 71 Cutlass Supreme convertible that is in excellent shape cosmetically, but it drives like a boat. CA bushings are shot and I'm sure the springs and shocks need replacement. Will also do the ball joints and tie rod ends as well as sway bar links. Got inspired by Rob's detailed post of his suspension rebuild from 2011 and decided to do this myself. But - I have a question about the parts. Looking around on the web I see all kinds of people saying Moog and AC Delco parts have really taken a nosedive in quality in recent years as they have outsourced all manufacturing overseas. I'd like to use more or less original type parts as the car is original. Have any of you had recent experience with these parts? Are they decent quality?

Thanks!

 

Welcome

I used moog springs this spring. The car rides much better now.
post some pics of your car.

where do you live in NC?

 

Welcome to the site, Moog parts are still very good quality. X2 on some pictures.

 

Welcome. Lots of options but I think you are on the right track with Moog front end parts and I like old fashioned rubber over poly. Search and someone here will have the part numbers for springs equivalent to the 442/FE2 pkg or station wagon if you want a little height in back. I've had good luck with relatively cheap KYB gas shocks on my Cutlass and other cars. To take it up a notch but still close to stock, add a rear sway bar (requires boxed control arms) if not already there and then a quick ratio steering box (also search here for the options). Will be way better than 45 year old stock but no GM A-body is going to be a canyon carver without major work.

 

OK - thanks for the responses. I guess I'll forge ahead with Moog. Just want to get it into good shape - I'm a conservative driver and not going to put much stress on it. I'm in Winston-Salem. Am attaching a picture - I think - Photoshopped our rescue dog Ranger in the front seat.

 

Nice, doesn't look like its sagging much.

 

Nce looking car. I'm in Charlotte if you ever get down this way. There is a Olds GURU in Clemmons. You should look him up. here is his website.

If you go visit Jim Michael and them in Clemmons, make sure to pet Rocket the cat. Not sure if Rocket is still alive. He was a big-*** tabby cat who had the run of the place...

 

X2 on the rear away bar and close ratio steering box. I went with junkyard low mileage Jeep Grand Cherokee steering box for less then $100 all in. It made a huge difference in how the road feels and how it drives.

 

Thanks for the tips. Not sure if I want to do the sway bar and steering box stuff. Don't know if I'll get down to Charlotte, but will certainly plan to hop over to Clemmons and see them. Would like to get some advice on removal of the right upper CA shaft. Seems like the AC stuff would have to come out or at least be moved in order to get at the nuts. So a guru would be helpful to give me some guidance on that.

 

You may need to take the belt of and remove the compressor from the bracket to swing it out of the way. Do not disconnect the a/c lines.

 

Yes, hopefully that will do the trick. Would hate to have to get the AC evacuated and recharged.
Thanks!

 

My car has Moog 5536 in front and PST "442" springs in back (I think they are equivalent to Moog 5409s).

Here's some spring info I archived a while back:

Thanks Kenneth. I ordered a bunch of parts from Rockauto. I was looking at the Moog 5450 springs and close to ordering them, but was not confident they were correct for a '71. Rockauto said they did not have a Moog HD spring for my '71 convertible, and the Federal site does not show it as compatible. I've seen that they have been used in '72s so should be the same thing, but was uneasy about taking a chance. I ordered the ACDelco HD springs 45H0071 figuring they would be essentially the same thing.

Nice looking house, too!

 

David
I have the same springs as Ken I love the ride

 

Aargh! Don't tell me that now - I've already ordered the springs!

Here are a few pictures...

 

Welcome
Nice Looking Olds

 

I am going through the same process with my 1969 Cutlass Supreme. I already installed the rear components and the front suspension stuff is sitting on a shelf awaiting install.

Boxed rear trailing arms
Rear Sway bar
Larger front sway bar
Moog springs (front and rear)
Bilstein shocks (front and rear)
New bushings (front and rear)


With the rear done I am seeing a tremendous improvement. I can't wait to get the front suspension installed.

 

Did you mean "house" or "horse" - that looks like quite a big dog!

I'm in Fayetteville. As you've already found out, there's great people here.
