Looking ahead at replacing my rear shock assemblies, and (reviewing old pertinent threads) possibly needing new LCA bushings or bolts, here is a Majestic Honda exploded diagram (in part):


Majestic lists the rear LCA group (#8 in the diagram). The original LCA in my car looks like the "plain/straight" #8 shown on the left. Also shown in that group are LCA bushings #12 and rear shock bushing #21.

The shock bushing #21 (Yamashita) is available separately for ~$20. But the LCA bushings #12 are listed separately "Discontinued".

The nearby assembly shown on the right (box tagged #7 or #10?) is not listed, nor are its associated bushings #13 or #20. However, the bolts #29 shown are listed separately for ~$10.

Questions:

1. Will the #29 bolts (described in the FSM as "Self-locking Bolt 10 x 1.25") work with my original LCA (presumably type #8) and my original LCA bushings (presumably type #12)?

2. Assuming I may need a new LCA bushing #12 (discontinued), will bushing #13 also work with my type #8 LCA?

3. If Q1 answer is "No", where may I obtain new LCA self-locking bolt for my type #8 LCA?

4. If Q2 answer is "No", where may I obtain new LCA bushings equivalent to discontinued #12 shown?

 

Hey Brian, what is the year of your Civic? The one shown is for a 1992-1995 Civic that's cast and has different overall length/angle compared to the 1996-2000 Civics come with a stamped "straight" version.

To answer your questions:

1. Yes, #29 bolt will work on either left or right side, as long as they remain used in bushing 12 or 13. They are tapered and shorter than the bolts being used on 20 and 21.
2. From factory, I do not believe the bushings are interchangable from left to right, due to the offset of thickness in the rubber and possibly the taper on the bushing itself for install. I suggest, visiting our friends over at velocityshop (https://velocityshop.com/) who sell replacement bushings via a brand called HardRace. These are great factory replacements that can you obtain in the event that you'd like to re-use your OEM arm. Otherwise, they offer a full replacement set of arms with the bushings already pressed in so that it's an easy swap.

 

Great answers, thanks. It's a '92 VX. I'm surprised left and right might be different, Majestic lists only a single LCA which suggests L/R application. I plan (pray) to reuse the LCAs, this is not an upgrade project but a daily driver. Until I try to remove the LCA and shock bolts, I don't know what I'll have to reuse. I'd like to have new parts on hand if I need them, so I don't have the LCAs removed waiting for parts.

Can the car be rolled around (not driven on the street) without LCAs and shocks installed?

 

No, without LCA's or shocks, the vehicle will sit very low and the wheels would also be bent out of wack a bit so unable to be rolled.

You should be fine with reusing your bolts and LCA's, as long as the bolts do not break. If you live in the rust belt, I suggest use some heat and the 50/50 mix of ATF and Acetone to breakdown that rust... broken LCA bolts are a common issue. Best of luck.

 

Update: I applied penetrating oil several times over several days, and did considerable tapping with a hammer. I was able to get the outboard LCA bolts to start backing out.

But the first shock bolt I tried is really tight. Using an 18", 1/2"-drive flex handle, supporting the socket with a block of wood, and putting maybe 100 lbs of my weight on the handle, I was able to get it to start turning, but I'm afraid I may be twisting the shaft.

Question: Will the bolt snap if it's going to fail, or will it twist? (I don't know what grade bolt it is.)

Update 2:

The first shock bolt I removed snapped. I removed the LCA w/ shock attached, cut the shock's nut off with a cutoff wheel, now have the LCA free with the bolt stuck in the original bushing. Been soaking with penetrant and hammering, won't yet budge. The rubber still seems good, despite the appearance in the photos, it's firm. I'd like to save the bushing in place.

How do I get the remaining bolt out of the bushing?

-

 

I took it to a driveline and gear service business, they tried a 50-ton press on it and the bolt wouldn't budge.The shop said they can remove old and install new bushings for me.

So now I'm looking for 2 bushings (R & L lower shock mount) as I don't want to purchase new LCAs. I looked at VelocityShop.com but I'd prefer an OEM style bushing.

Referencing the diagram in my OP, Majestic sells #21 a Yamashita shock bushing:

The price is reasonable, as long as this item will work on both rear LCAs (they don't sell a R and L).
