Two years ago I´ve bought my Aurora, which was imported to Austria back in 1997. Now I have moved to Switzerland and took the car with me. To get it on the streets again I had to change/renew a few parts. Most repairs worked well, but since 1,5 years I am searching for the correct control arms.
Everytime I order the bushings or the complete control arms, I get the wrong ones: The front bushing should be mounted vertically. But always horizontal mounted bushings are delivered. (see pictures, please)
Each supplier I´ve contacted, from USA or Europe, told me, that these should be the correct one but they aren´t. Rockauto told me: "Designs may change as it is not uncommon for manufacturers to supersede parts or make improvements to them." But they don´t have those "unsuperseded" parts.
Is there anybody who had the same issue or who knows where to get those parts?
Sorry but I think you are SOL. That is the hybrid control arm. It has one horizontal bushing and one vertical just like the stamped steel 95-96 control arm but it is aluminum. Except the horizontal bushing is a different O.D. than the 95-96. No aftermarket. You may be able to find something through the dealer. Likely NLA though.
Cut off the existing mount, then fabricate and weld on one to accept the '98 control arm?
There are a few places that claim to have the left one in stock (GM25660352), but no right sides or bushings to be found it seems...
You can cut the mount off and flip it 90*. A few on the Riviera forum have done it. You can also swap subframes to newer style. I considered these options to swap to newer style control but settled for rebuild and poly on my 96-96 control arms.
The easiest thing to do honestly if you cannot find the parts is rebuild a set of 95-96 stamped steel control arms and press in new OEM bushings. FWIW, I will mention Grand prix et al stamped steel control arms do fit but they push the wheel 1/2" further forward in the wheel well. That can be a deal breaker with wider aftermarket wheels and wider tires.
Good luck in your search. Let us know if you find a pair or what route you decide to take!
Thank you all for your thoughts. It seems that I´m almost out of "easy" options. I wonder why these parts are no longer available. Are there that few Auroras built with these "hybrid" control arms? My supplier for GM parts tries to find at least bushings that might fit from another model atm. Because, as tigger mentioned, some stores have the left control arm in stock. But the bushing on the right hand side is which I have to replace immediately...
What I´m going to try now, if no other part is going to fit: - get the bushings recreated by a german factory - or, the most expensive way, try what sall and tigger suggested: swap the subframes to the newer style.
But I won´t let my Aurora down. ;-) I´ll keep you up to date which way - hopefully - worked.
There were no parts of GM for my car to get. But we now found out that the bushings of an Opel Vectra from 1990 fits nearly exactly! My mechanic only had to add rows of little solder bumps all around the bushings, so he was able to press it into the old control arms. Works!
BUT... As soon as we fixed it... my Aurora gave up her live... Her V8 stopped working on the streets (on my way to import it to my new home state...). Back in the garage we first found out that the fuel pressure is too low. So we put in new spark plugs and cables and bought a new fuel pump. Perfect pressure, sparks - its all there now - but it is still not working. The engine starts and runs if we spray in fuel directly through the air filter. If we start with keys, engine gets no fuel, everything remains dry.
GM Switzerland told me that the problem could come from the ignition lock or the engine immobilizer. Both may be also not available. They told me that the only thing for me to do is to kick those 1,7 tons of masterwork to the junkyard...
What??!! Really?! What are your opinions about that? Has this occured to anyone else here?!
If it cranks I'd say it is not a security/key issue. Can you hear the fuel pump priming with the key in RUN/ON? It may be possible if you bought a fuel sender assembly where you had to cut and solder ona new plug that it was improperly wired.
