so, how loud is it with Heim joints?

[GIG4FUN]

My LCA's bushings are gone. (BMR's) I am wondering about my patience with the adjustable lowers with heim joints. What should I expect? Chime in if you know... I think I'm buying them next round.

I don't know about your patience, but mine lasted 2 weeks, as soon I got on the road I knew they had to come out (BMR's poly/spherical adjustable)
The only way they would work is if you were to install them with line reamed nominal bolt diameter relocation bracket holes...and have the spherical bushings (alu) replaced with custom made ones reamed to nominal diameter bolt size...
Otherwise be prepared to live with a constant tock-tock that will elongate your bracket holes...
I just installed the greasable Spohn poly/poly adjustable LCA's in the hole below the one I was using because of elongation...
Cheers

I've been running the BMR poly/spherical adj LCAs (#TCA021) for well over a year, and I have no problem with them. Yes, they do clunk a little, but I really only hear it at low speeds on bumpy roads. Cruising down the highway, or on smooth roads, is not an issue. And I just had mine out a few weeks ago, and I noticed absolutely no wear and tear on the bracket holes. Everything was just fine under there.

I'm not trying to say rog06gt is wrong... just saying my personal experience has been different.

How did your poly bushings get destroyed? I have them and if I can avoid damaging them I'd like to do so.

I just replaced my BMR adj poly/spherical with BMR adj spherical/spherical because I went through 2 sets of bushings in 2 years. I do not find that they are that noisy. At low speeds you do hear some clunks, but usually low speed driving means I have the air and tunes going so I really don't hear it. At high speed driving they are silent. During aggressive driving they make a little noise, but they are supposed to

2 sets of bushings in 2 years? That's not acceptable. Why are the BMR bushings wearing out so fast?

The bushings are not wearing out, they are failing. They split along the axis of the bolt/sleeve which allows the LCA to move fore/aft. Not good.

I did notice on the spherical/spherical setup the adapters are offset on the axle side causing the LCA to be mounted almost aligned with the body mount, where as the spherical/poly setup does not have this side to side articulation. Perhaps that puts some extra load on the poly end under heavy cornering (where I believe they fail)

thank you..

I wanted to thank you guys for your feedback. I went ahead and bought the 1/2 heim 1/2 poly adjustables for the rear. I will add my opinion in this thread some day after the install.
I had a 4 link with full heims on my '69 Fstbk 466 CID Pro Street and it could not be worse than it and I didnt mind that noise...(I really really miss it as a matter of fact.... !)

the do clunk a bit...but not unbearable for me.

Every manufacturer has had problems with the LCA bushings failing.

I don't blame the manufacturer. I have Steeda Billet's on the wifes and BMR on mine. I hit mine pretty hard a lot.... I will say though that I used energy supsension,s lube and coated them by hand. I did not blow them out with a grease gun. They have a life span just like everything else.

There is at least one manufacturer with none or a very small failure rate.

Granatelli???

 

[Kevin@PMP]

Granatelli???

No comment.

 

[thump_rrr]

As long as they're broken down and hand lubed they will hold up just fine.

I took Steeda Billet LCA's apart for inspection after 12,000 miles and over 200 S/C'd runs with no trouble.

 

[GIG4FUN]

some of you are being naughty....

 

[JonW]

And who would that be?

 

[169stang]

I'm not sure, but I've heard of Steeda, BMR, CHE, Granatelli, UPR and I think that's about it. I really haven't paid attention to any others.
