Exclamation

Just got off the phone with Energy Suspension Tech Support. Be advised they are now aware their inner sleeve for the rear bushing in the front lower control are is too small for the stock bolt. They offered no fix or help except for ME to find a smaller diameter bolt or have inner sleeve bored out to proper size. Course they did state their NEXT catalog will NOW contain a footnote "except police and/or taxi vehicles". Anyone able to help/offer/provided size and/or source(s) of smaller diameter bolt or how to have the inner sleeve bored out so I can get my 96 9C1 back on the road. Thanx all for the info & letting me vent.

I have a set in the billet LCA I made but have not yet installed. The ID measures .560. I tried the stock bolts and they fit through. I think they must be 14mm. If not 14mm works out to be .551 which would fit.
For resizing for 9/16" bolts (.562), install the bushing and then the sleeve. Once it is captured within the bushing try drilling to 9/16" and then go 1/64" oversize to 37/64". I think the press fit is sufficient to prevent the sleeve from spinning. If I'm wrong, any machine shop with a lathe could do it in minutes. The plating on the sleeve wont last long anyway.GL. If you feel desperate, mail them to me and I'll do them in a lathe for you, NC.

Question

Paul, thanks for the help. Want to be sure I understand. While the sleeve is IN the bushing use a 37/64" drill bit to enlarge the inside diameter. You believe the bushing will hold the sleeve from spinning & the gold coating taken off is no big deal for it wears off anyway? Are 37/64" drill bits relativly easy to find? And, if I can't get that to work....give the needed inside diameter to my local machine shop for this is a pretty simple task for their type of work without damaging the outside of the sleeve? Thanx a million...I was stressed !!!!

smassie,

Sorry to hear of your problem. The bolt size did change, at least on the 91-96 cars. I use alot of Global West bushings, and the inner sleeve is offered in 2 sizes for different applications. Pre-91 cars were 9/16", I think.

Looking at the GM parts list, all 91-96 cars use a 14mm bolt on the lower control arm pivots--there is nothing special on the 9C1's.

If others have used an Energy Suspension kit with no problems, I'd have to assume that there was a packaging problem, and you somehow ended up with bushings that had the wrong inner sleeve installed. I'd persist with Energy to make this right if I was in your situation. It is alot easier for me to say that with Energy just "down the road" compared to your location on the other side of the country--but I've never dealt with them, but I do know they aren't interested in having anyone into their facility, and I've only ever been able to get answers to my questions through retailers, so you got further than I ever did. If I could find my ES catalog, I'd look to see if there is any listing difference by year, though that alone would not show the sleeve diameter difference, unless it was in a footnote.

Good luck, let us know how things turn out!

Smassie88, yes that is correct. Make sure the bushing is installed in the control arm first or there won't be enough compression on the sleeve to prevent it from spinning. I don't think 37/64" drills are etremely common but they are around. A well equipped hardware store should have one.

Question

Ok, I'm pretty much an idiot when it comes to suspension, but I just read Scott Meuller's suspension guide and it mentioned the front ball joint extensively. He said that in late '95 and '96 they used a 5/8" ball joint and before that they used a 9/16". Would that have anything to do with the problem? If not, can anyone put up a link that helps to explain all of this suspension mumbo-jumbo so I can know what I'm talking about? [img].gif[/img]

Here's the link I talked about

Talking

OK, here is the final post for this topic, I believe. Energy Suspension came through, the 2 new larger sleeves came Priority US Postal Service today. Inside diameter was in fact 1/16" larger. Bolts fit through, so front control arms were installed just a short time ago. All went well now that the bolts fit through. The lesson I learned here....make sure ALL sleves are correct. I would like to thank everyone who offered a service, helped, provided the important information that made Energy Suspension agree they may have enclosed the incorrect sleeves. [img].gif[/img]
