Post Urethane Bushings - Yes or No??

I have an old car that needs the lower control arm bushings replaced. I have three questions.

Is it worth the extra money to buy the Urethane bushings over the stock rubber ones?

Are there any disadvantages to having the urethane bushings?

The upper control arm bushings are good. Can I install the urethane bushings on the lower control arm, and leave my stock rubber bushings in place on the upper control arm??

Thanks for any advice.

I just installed a set of chassis engineering control arms on my 65 Beaumont and could not believe the difference as compared to the stock bushings. It has a quiter more controlled ride with no axle hop or chassis shake on rough roads. I would definetly go with the urethane bushings. Its a good idea to spray down the bolts with rust penetrant a couple of days before you tackle the job. Good luck

Jim, I advise to replace all of them if your going to replace any of them, one less thing to worry about. I recommend the urethane bushings, they aren't mushy like the stock they are self lubricating so they don't dry out, and they reduce viabration a bit. I lovem', I say its worth it but thats just what I think.

Most cars I have installed urethane bushings into end up having squeaks later in life, this is always solved with a little shot of silicone release spray or WD-40. I like the Delrin bushings better if only because they are less squeak prone. I built my Vintage SCCA RX7 with all nylon bushings and I thought that was the ultimate, I made semi spherical rod ends for the sway bar with aluminum cups and that car was SOLID! I personally could not see a down side to hard bushings in the suspension, the car drove like it was on rails with none of the harshness that was supposed to be the downside of this type of modification. I guess rodders are just more tolerant of minor inconveniences for the added performance.

I dont know what type of vehicle you are talking about but check out global west they offer a nylon bushing ( i think these can also be purchased at your local bearing dealer) these allow for good suspension travel (like a bearing). i have heard quite a few complaints about urethane bushings . Mostly people complain about noise and in some cases. didnt like the ride after the change. I have read some books on suspenpion ans car handling and they swore by these nylon bushings . just a thought. good luck.

Jim, What ever type bushings that you decide to go with I would change all of them. My thinking is if you do not keep them the same the softer ones will be taking more punishment and will not last as long.
