View Full Version : Body Mount Bushings
murph's 68 Jul 4th, 03, 12:59 PM I am ready to order body mount bushings for my car. I have decided to go with poly bushings. I just cannot bring myself to install solids on a street driven car. I have read alot of old posts that recommend solids and also alot that recommend poly.
Whose poly bushings should I buy? Are they graphite impregnated or not?
Thanks,
Murph.
Mountie Jul 4th, 03, 08:02 PM Well I installed Energy Suspension Graphite impregnated urathane mounts. It was ok but I ended up switching to billet Aluminum and I'm much happier for it.
Good luck !

purple69ss Jul 5th, 03, 12:02 PM Performance Suspension Technologies has a wide selection of bushings for body mount & suspension
ORENCH Jul 5th, 03, 05:05 PM Are this solid bushings from Summit any good, or you recommend any other brand. For $43 they're kind of affordable for me. :D

murph's 68 Jul 5th, 03, 09:06 PM Ah yes, the dark side. David, I have read many of you post's and have been on your web site for quite a bit of reading. I am just unsure about these body bushings. I have heard so much about the solids but just don't know what to think?????
It seems to me like this will be too harsh for me. I will put about 500 miles per year on my car and it will be mainly street driven. What is the best thing to go with???

novaderrik Jul 5th, 03, 09:31 PM go solid- you WILL like it. you will barely notice them. in fact, the car wil lfeel sooo much better than with rubber bushings. why did they put bushings in there at all, anyways? the old Novas and Corvairs don't have any rubber biscuits isolating the chassis from the body, and neither do all the old unibody Fords or Mopars. just how is it a good thing to have the body floating around on the subframe like that?
chicane67 Jul 5th, 03, 09:35 PM For only driving 500 miles a year, you will never know that they are there !!!
You want harsh, put in u-thane control arm bushings and run KYB's.....and then put 17's on it.....
Dont sweat the sub frame bushings being aluminum. If you really are only going to drive the car 500 miles a year you'll neve known they are there. I run 700lb/320lb front/rear springs with a 16" wheel and tire, Del-a-lum solid control arm bushings and re-valved Bilsteins on the street and have done so for roughly 10+ years. The ride quality is still compliant and impressive to this day. The sub frame bushings were the addition with the least physical increase of road stiffness.
RickD Jul 6th, 03, 02:53 AM When I put solid GW bushings in, I noticed no increase in harshness. On the other hand, Energy Susp poly motor mounts significantly increased ' the buzz'. I drive 2000 or so miles a year and don't mind.

murph's 68 Jul 6th, 03, 07:23 AM O.K. I currently have Hotchkis/Bilstein/Energy Suspension out back and all 35 year old originals up front. I am working my way from back to front with the suspension/bushing upgrades. I plan to go with the Hotchkis springs and 1-1/8 sway bar/Bilstein/poly bushings up front. So if I go with solid on the body bushings is there a prefered supplier for them?
davidpozzi Jul 6th, 03, 07:51 AM I recomend putting in solid bushings. If you don't like them you can allways put in polly or rubber and sell the aluminum bushings to someone else. At least you tried it and have gained some knowledge on the subject.
If you can find a forum member in your area who has installed solid sub bushings, go for a ride with him and see how you like the ride.
You really don't want your subframe to move separately from the unibody. It makes the car feel sloppy. The best descriptive word I can think of is Tight, the car feels more solid, less jiggling and rattling around, which is more annoying than any supposed increase in harshness.
I've ridden in a bunch of Camaros with solid sub bushings and they rode great. As mentioned above, there are lots and lots of cars on the road without a separate subframe. Mustangs have a full unibody and I wouldn't say they are harsh riding.

murph's 68 Jul 6th, 03, 10:26 AM I was just starting to think exactly what you stated David. I'll put in the solids and see how they are. I can always go back and change them if I don't like the ride.
I have not done alot of research on installation of the solids. Will they bolt right up with the stock cage nuts in the frame? I would think so. Is Global West the best place to get these?

RamJam Jul 6th, 03, 11:16 AM If your body bushings were never changed and your car is all together meaning fenders - hood - doors are all on. Get ready to make adjustments after your install because it's almost a given that some panels will have to be re-aligned. I know from experience. :mad:
murph's 68 Jul 6th, 03, 12:23 PM RamJam,
The bushings have never been replaced and the car has never been taken apart. Do you still think the panel alignment will change?

RamJam Jul 6th, 03, 12:35 PM Sorry, I'd have to say yes. :(
HwyStarJoe Jul 6th, 03, 05:47 PM And you better prepare yourself for some ugliness. I mean, rust\rot around the mount holes. You can reuse your old hardware but get new bolts\washers.
The solid bushings mounting flange\lip will have an outer diameter of exactly 1.5". When new, the frame's mount holes were 1.5". If they're rotted now, the frame and body can move around. Not good!
If needed, I'd repair the subframe mounting points no matter which bushings you install.
chicane67 Jul 6th, 03, 07:30 PM Excellent point Joe! I have run into this a few times and it gets messy if that problem exists. And that would be the time to fix it........
davidpozzi Jul 6th, 03, 07:59 PM I would suggest to change the front two bushings last, and if they need to be cut down or spaced up to fit, do so. That way the front fenders will not need any adjustment. If you force the front bushings in there or have to pull the fenders down to the bushings, it will pull them out of alignment.

RickD Jul 7th, 03, 03:13 AM And if you do have to repair, do yourself a favor and but some 1/8" plate and make them. The kits are alot of money for something simply made.
Or you can go the large washer route that some have.
murph's 68 Jul 7th, 03, 08:39 AM I got the note on checking the frame sections for rust and damage. I will do that.
If the panels lined up in 1968 with new bushing and the bushing are now worn, shouldn't this make the panels misaligned now. When I restore the bushings back to factory height shouldn't panel alignment then return to the location from good ole 1968. Is this a stretch? What am I missing?

I live in Dundee, Ill. so if we run into each other I would gladly give you a ride in an aluminum bushing car.
Start putting penetrating oil on the bolts/nuts now even if you don't make the switch for a year it will make the removal process easier. Do this every time you touch your car. This happened to me and I think it helped me easily get the old stuff off.
I bought mine from Detroit, speed and Engineering and am very happy with the quality of the bushings and matching stainless steel bolts/ nuts. Use anti-seize when installing the new ones. These cost slightly more but it's not something you are going to replace for a long time so do it right the first time.
I was pleasantly surprised when I first drove the car after the new bushings were installed. I wasn't sure how it was going to ride but I believe it rode better with the aluminum bushings than with the old rotten original stuff. An annoying vibration also went away. I can actually use my review mirror above 50MPH.

murph's 68 Jul 7th, 03, 03:37 PM Ray,
I have already started spraying down the joints. I started when I finished the rear suspension about 3 weeks ago. A couple of applications a week seemed to work wonders on the rear suspension.
I was looking at both the DSE and GW bushings. I was leaning toward the DSE's.
I work up in Bartlett and I wouldn't mind getting some first hand knowledge before ordering. Everybody here at TC has done a good job convincing me this is the way to go but seeing yours would be the icing on the cake. If not I will probably end up ordering them and trying them to see if I like them.

Poncho Jul 7th, 03, 04:29 PM That's what I found Murph. When I replaced my busted a$$ rubber biscuits for aluminum the panel alignment and mis-match improved. It's like putting it back to where it <should> be... If someone moved panels around later in the car's life then you might have problems... IMO
RAY NORLIN Jul 8th, 03, 12:00 PM Murph,
I go to the cruise at Rt 20 and Roselle Rd (Bloomingdale Rd) on Friday nights frequently. Don't think I will be there this Friday but I will let ya know if I am. I also go to Beef Villa on McLean and Spring (Hopps)in South Elgin on Saturday nights.
I drive a gold Z28 with black stripes with a blown small block under a 6" cowl hood, all black.
I did not have to do any realigning of panels after installing the DSE bushings.
edd Gordon Jul 8th, 03, 12:31 PM Solid bushings and welded subframe connectors with urethane bushings front and rear with KYB shocks on my last 68SS and rode and handled fantastic. I may do the same thing to my present 68SS just depends on time and money.
Mountie Jul 8th, 03, 06:35 PM Well there seems to be a lot of posts on body mounts so I decided to show the ones that I'm making and will be offering for sale including all the hardware!
