I have need of replacing the cradle bushings. The parts book lists 1627359 as the cushion. Is that all I'll need? Is this number still good? '90 Reatta.

I have a note from a Reatta owner saying the parts listed for a Reatta were no longer available and they used 1627359
at the time it was listed for the Riviera.

Those bushings are interchangable with a lot of Buicks.
My 2000 Park uses the same bushings.

Rubber = $80 each!!!!

I've got to replace all of mine too. This is one of those times you'll save a lot of money by using gmpartsirect.com

Just a bit more info for those interested:

I have purchased 6 of these to replace all on my 91. They are genuine GM parts, not Delco (GM SPO boxes on all) and got them through my dealer.

My price was about $23.00 a piece. Granted, I get wholesale pricing (what the dealer would charge a shop with an open account) but that is about a 40-45% discount over retail, so regular price shouldn't be more than about $60 each. Whoever is paying $80 apiece should have brought their wet suit because they are getting hosed by their supplier.

I don't have the part number in front of me right now (at office, info is at home) but I will try to post the number I ordered later tonight. It is interesting that all 6 were the same # based on current parts catalog. In the FSM they call out 2 different types based on a color code which would have been stamped on the original parts, probably long gone on our cars with original bushings. Also, the parts I ordered were listed for car code EC97(Reatta Coupe) whereas Riviera is EC57, so the correct ones should be available.

Yes, there are also spacers, nuts and bolts. I did not check on the hardware, but was told by my parts guy while the spacers are available, I should be able to reuse them (all metal part apparently) but that remains to be seen. Hopefully I can get the bolts and nuts removed without any breakage.

Hope this helps

Ok,

I finally managed to dig through the big box-o-parts I have been accumulating for my Reatta and the cradle bushings I purchased were marked 1627359, as per the first post of this thread. FWIW, these were listed for the Reatta in the parts catalog at the dealer. Likely they are used for the Riviera as well, I'm guessing that this one part # super cedes all earlier variations/numbers for both the Reatta and Riviera. Anyway, this should settle the confusion over which to use.

As mentioned, the metal washer should most lilely be reusable. If your car has spent any time in salt country you may be surprised by the condition of the bolts. Several of mine were corroded inside the bushing and were less then 1/2 their original diamenter. That represents maybe 10 to 15% or their original strength. They're known to fail!
They're a metric bolt of course but they can be purchased from any good Fastener/ Bolt supplier.
Go with Grade 8 in a zinc chromate finish, apply a liberal coating of Crown Rust inhibiter at assembly and they will come apart in the future in good shape, literally guaranteed!

Didn't we have a thread just a few months ago by someone who replaced them. He reminded us that when removing the bushings that attach to the lower A-arm, be careful to ensure that the strut springs are compressed. The spring exerts a downward force on the A-arm so when the bushing bolt is loosened, look out. The earlier thread had part numbers for the bushings, the washer and the bolts. He also pointed out that the nut is probably just tack welded in and tends to break loose before the bolt is loose. I don't think there is access to the nuts with a wrench.

I haven't thought about nuts just being welded in there...Would it be possible or easier to just cut a minimum hole in there, remove the old nut and replace it, tack a weld, and reweld the cavity closed?

I would certainly go through a lot penetrating oils and heat to loosen those bolts before I would undertake that kind of work. I gotta say, Phil, your solutions are not always elegant, may often be labor-intensive, but you do go at the problem head-on and always end up getting the job done.

I tend to take repair situations literally..."it's broken, it needs to be fixed, whatever that entails"

However, in this case, I'm going to investigate if it's easier to drill out the broken bolts, tap, and install heli-coils. I spose the bolt could be a larger diameter but although some people are against heli-coils I don't think they're bad. I've seen them used for cylinder heads before. Being that they're stainless steel they're actually going to be stronger than the stock metal
