So I am planning Moog 1LE-style rear LCA Bushings (p# k6178) to upgrade from stock bushing, and would like to know from those of you who did this swap, what did you notice different?

TIA!

As the English would say on the London Tube, 'please mind the gap!' err gaps in this case:

Well, I went from stock to boxed and 1LE solid bushings,
and I can't say I noticed a thing. It just seemed like a
good idea. I imagine a little harshness might show up
but it didn't strike me at all.

I did too many mods at once to tell if they made a difference. I did my shocks, springs, and LCA Re-Location Brackets at the same time.

How hard is it to replace those rear bushings? Are they pressed in or are they removable by hand?

In a post from '06 on this site, Strano says they press in/out super easily:

You have to press the old ones out and press the new ones in.

I was able to press them out with a Harbor Freight press
but couldn't get them loose in a 6" bench vise (redneck
arbor press). Used sockets inside & PCV pipe outside as
an anvil.

I changed mine with a vice.

Which Harbor Freight one did you use? The 20 Ton Shop Press?

I would like to replace my stock bushings with new Moogs as well... I can't imagine you would feel much of a difference without the gaps in the rubber.

Any reason your keeping the stockers? For the work involved replacing the stockers, a set of aftermarket LCA's aren't much.

Yea, but I'm not planning to box mine...

Are you trying to say the stockers are better than an aftermarket set?

You didn't read, did you?

I clicked the links, but no, I didn't waste 15 mins reading their complete take on LCA's. I see they didn't like poly. Are you just trying to not use poly?

Those two articles are interesting. Some good information...and a lot of crap too...almost flat out lies. Just like everything else...take it with a grain of salt.

Sorry for the noob questions that follow:

I have new shocks on factory springs in all corners.

Does replacing bushings eliminate loud thuds while driving on minor uneven roads?

Car has 96k dd miles, at this point regreasing bushings is out of question and replacement is only proper choice?

TIA

So I'm interested, Old Cobra Guy, just what did you find 'just flat out lies'?
I get what he is showing in the analysis, and don't totally agree with all his assumptions, but the general gist of what the numbers show is valid. If you want a drag racing suspension, sure, get rid of the rubber, get rid of the stamped arms. Go to something really stiff in compression and a new torque arm.
But, for DD or autocross, with the lca angles being wildly different side to side, you need torsional flexibility along the axis of the arm. You can do it either at the bushing, with a roto-joint, heim joint, or whatever,. But if you still want a rigid lca, or you can do it with a flexible stock lca and a stiffer rubber bushing to help with the mushiness in compression.

Have you considered rod ended LCA? I've had mine for years and I don't see myself ever going back to bushings. They are louder over big bumps but otherwise I don't hear them. Solved a lot of weird issues I used to have when powering out of a turn.

I bought a set of the "Johnny-Joint" equipped LCAs last year, as I was being picky and wanted to correct a slight "toe" issue with my car. The good news, I was able to get the car on a 4 wheel alignment rack, and get the rear wheels "dead nuts" in line with the fronts.

The not-so-good news, was these joints (as well as any rod ended joint) are too unforgiving for the crappy roads where I live. They certainly do allow the rear axle to smoothly articulate over dips in the road, and not bind up like a bushing would, but they transmit way too much shock to the undercarriage of the car, when hitting expansion strips or other sharp impacts, IMHO. I took them out after a couple of months, and as soon as I get a little ambition, will probably put them on e-bay.
