Regarding the Front Control Arms for a 1997 Riv, this Write Up has some excellent pictures of the 97 and an alternative bushing that was used with some machining to fix his front end. Y'all have probably already seen this but I just thought I would bring it back up since there has been some talk of the 97 being the oddball year. Go to Arttu80's info.

Hi,
You can get the bushings, they come as part of the complete lower control arm assembly, which gives you all new bushings and ball joints. Don't know if you can get them from a GM dealer in Finland, they are pretty easy to get in the US and although they are a little more expensive than buying the bushings/ball joint separately, they are easy to put in since the assembly is already done.
Anyone know where such a beast exists?

I got mine from monsterpartsonline.com. They were for a '98, not sure how availability is for other years. You should be able to call a dealer and get a part number if they still exist.

Thanks Derek. I've been checking out sites trying to locate a pre-assembled control arm for my '96 with no luck, which means that when I do decide to replace the ball joints, I will probably be dropping the control arm to grind the rivets off and to replace the bushings. So my question now is, how hard is it to press in the new bushings once the old ones are out?

With a hydraulic press that some Parts stores still have, very easy.
Are the bushings available for your year, I thought they had to be custom made, or I could be way off base, IDK. You should use a press to remove and install so as not to deform the control arm.

the bushings on the steel arm are very difficult to replace. at the factory the rubber bushing is cylindrically compressed and then inserted into the arm and then allowed to expand. to get them out is a piece of cake. i just heated up the arm and when it got hot ,gripped the inner sleeve bonded to the rubber bushing and twisted the bushing out. replacing the bushing i had to get a 8" long grade8 bolt and nut. position the VERY lubed bushing onto the arm,put the bolt through the bushing and out the other side of the arm housing.now thread the nut onto the bolt,before hand ,have a good selection of big washers of various diameters that you will have to install on either side of the housing,and start impacting the bushing into the arm. the bushing will start to compress,at this point you have to back off and start over. and in this way you will incrementally pull the bushing into position.PIA. or you can take it to a shop and watch the mechanics scratch their heads for days wondering how its done. or you can find someone who has done them before and take it to them. i took mine to a local mechanic who complained how impossible it was for him a 2 guys to install them. the problem is that the bushing keeps squishing in the press,you have to have a way to compress the bushing. at that point i just figured out how it should be done. and i did it. i guess the best illustration is ,if you recall, is one of those push pops. the ones where you push on the stick to make the pop come out the top. hope that helps.

Thanks for that robo, I forgot that 95-96 had steel arms. But why do you say to back off and start over? Also, I found this video showing a bushing removal process. Is your idea kinda like it?.....

well..thats the general idea. thanks . i didnt know utube had those? i found this one that approximates what i came up with. it aint easy! there is no way one can remove the oem bushings with out the aide of a really big impact gun. no way! by hand? forget about it!
the bushing on the steel arm is so mushy,that as soon as you deform it,it wont go any further.in the video its made of polyurethane. if i were you,and instead of trying to futz around with the nearly impossible oem bushing,go to mcmaster carr and buy a length of polyurethane rod. i have a 90 durometer rod in a 45mm diameter for the rear control arms. for the front steel arms,the oem bushings measure 47mm in diameter x 50mm wide. mcmaster sells lengths of polyurethane rod in 6" to 48" lengths.. a 12" rod should be enough to do the 2 arms. the closest diameter to our oem is 50mm. you would have to shave it down a little. this can be done on a lathe. part # 2656T63 if you go the poly route,just bore out the poly rod to the diameter of the oem inner steel sleeve. after removing the oem rubber,by any means necessary, save the sleeve. and reuse it for the poly bushing.
i have half of this swap completed. ill be the guinea pig and keep everyone posted

edit to above post the poly rod that ive had for the longest time,the part #2656T63 , is the wrong poly to use.i have to find out more tomorrow,but the poly i ordered so long ago,is a very soft shore. its a high durometer,but its shore is soft,meaning that it can be easily gauged.i think that's how it goes. I'm really getting fed up with all this poly/rubber nonsense. i am just about ready to order spherical bearings all around. i already have the fronts ordered. #91634048 control arm bushings. from speedwaymotors.com. they will fit perfectly,maybe just a little short. but they come with spacers and will spruce up the handling of the riv incredibly. the rears are next. actually,the poly rods are more expensive than the sphericals. what you save in $ you gain in road noise. Vegas is pretty smooth. so i ain't too worried.....

mine's lower ball joint and suspension really needs some new parts. I have been scouting the web for some brands there are Koni's and KYB's can i ask if the moog brand is any good? thanks in advance.

moogs are fine. they make poly bushings for some models but not ours. any aftermarket brand will be no better than stock. sorry to kill buzz. moog makes poly swaybar bushings that are better. to really make your car handle you would need to have poly bushings custom made or, buy 2 part poly and make them yourself. either way,if performance is what your after in the suspension department,ya have to fabricate them yourself. if you want to stay stock,any brand is good. as for ball joints,they are all pretty good. as usual,oem is big $s,aftermarket MCQUAY-NORRIS makes a good one for the $. even lower priced 1s are ok. $55 and up for the premium brands. rockauto.com is a good place to shop.

I know this is an old thread, but I have found the front control arm bushings for the 1997 Riviera.
ACDelco 45G9177
Seem to be plentiful in supply. I have cross checked this bushing several times and they all refer to 1997 as a fit. If I am in error I hope someone will correct me as I plan to purchase a pair of them.
Just this past week we replaced the right lower control arm on my wife's 03 Regal and it was a snap, less than 40 minutes lug nuts off to lug nuts on without a hoist or impact driver. I don't see this as being any more difficult than her Regal other than having to press the new bushings into the control arm instead of a straight swap out of the control arm.

What is the price and location for purchasing the bushings?
Just type ACDelco-45G9177 in Google and they pop up everywhere. This guy has free shipping for $28 and change each.

Yes, I'm afraid that part application is an error - you can't use it... We've found out over the years that those ding-dongs in Detroit designed a different control arm for virtually every frickin' year of these cars! You can see some of the differences on page 2 of this thread, but basically the progression was thus:
'95 - Conventional steel control arms with replaceable, perpendicular bushings; '96 - Conventional steel control arms with replaceable, parallel bushings; '97 - Aluminum control arms with non-replacable perpendicular bushings; '98 & '99 - Aluminum control arms with non-replaceable, parallel bushings...
Except for someone with better-than-average machining skills and tools, the aluminum arms like yours & mine have to be replaced as a whole unit when a bushing goes bad (usually the vertical one I believe.)

Guys,
I have a question in regards Torque specs:
What is the torque spec for the Torx bolt and the bolt for the horizontal mount? and if you also have it for the Ball joint nut?
Help is always appreciated.
Thank you.

117lbs. A better idea is to get rid of it and replace it with a hex bolt.

Is 117 lb-ft for both bolts? also I'll be considering replacing the Torx bolt if I can. Do you happen to have the torque specs for the Ball joint nut?

The arms are not rebuildable. Order the complete arm assemblies at Rockauto.
