Badazz 97 TA

iTrader: (18)

I currently have UMI single rod ended LCA's and panhard bar on my car. I can tell my passenger LCA rod is worn out. So im thinking of just swapping to the roto joints. Been searching around the site for opinions. Not much came up. Some say there quiet others say there noisy and wore out quickly. I know there somewhat new design so there wasnt alot of long term opinions out there.


so whats the deal. Are they worth the $50/piece to upgrade? just trying to justify the purchase with real world results before i decide.

Do you like them?
How are they holding up?
How many miles do you have on them?
Noisy, quiet?
Do you have to tighten them alot?

i just installed my roto-joint panhard bar a few weeks ago so i cant tell you about how they wear out but definitely not noisy.

I have had mine for about a year now with zero complaints. I think it drives better than with the solid tubular LCA's I had with poly ends.
I have UMI's LCA's with the roto-joints.

I bought a pair of aftermarket rear LCAs, with the "Johnny Joints" on both ends, in an effort to correct a slight thrust angle situation with my '96 Z-28. They did an admirable job for that. However, I found them pretty "non-compliant" for street use, so I took them off the car (and actually, would like to sell them).

FWIW, the roads are pretty rough where I live...

The Roto-Joint shouldn't add any noise to the vehicle and will not wear quickly.

However this is a semi-solid joint, the rubber bushing is replaced with a spherical ball that rides in a Delrin lining. The Delrin will absorb some hit but not like a rubber bushing does. You will feel more with this set up more then what a rubber bushing offers, your tolerance to this depends on roads, other vehicle mods and overall what you want to feel from the vehicle. For example I have had the same rod ends on the front of my vehicle since August 2006 and I have encountered 30,000 miles over this time period. They still feel and sound the same as day one and I don't notice them much. I do keep the underneath of my car clean and lube them when its on the rack. A lot of time harshness from a solid end gets mix up with noise I feel.

I run Roto-Joints on the rear suspension and find them to be unnoticed.

I hope this helps,
Ryan

What are the advantages of the rotojoint?

UMI's roto-joint is essentially a newer generation of the Johnny Joint which is made by Currie.

Google "Johnny Joint". The first hit should be Currie's page. Watch the video for an excellent description and demonstration.

UMI's version:
- Uses Delrin bushing instead of poly
- Ball is chrome moly instead of heat treated steel
- Uses screw-on side with lock screw instead of snap-ring

IMHO, the UMI version is better because of the above differences.
- Delrin is a better bushing material for this application than poly
- Chrome moly is stronger
- The screw-on side allows you to tighten the joint as parts wear.

However, the Johnny Joint's bushing has holes to allow grease to get in, which is a nice addition to make sure grease gets in between the ball and bushing when you grease it via the zerk fitting.
