Has anyone had success freeing these without shearing off the bolt head? I PB Blastered what I could, then I put some torque on the bolt head this afternoon. I didn't have a good angle and didn't want to push it just yet. The nut on the back side of the bolt appears to be welded to the frame. I don't want to bust the nut just yet, because of experience with doing this on one of the rear control arms. I am supporting the car at the usual side jacking points with two jackstands. Might I get an advantage freeing these bolts supporting the engine (via a jack, some blocks of wood pushing up on the oil pan)? I'm thinking the weight of the engine is still acting at least partly on the bushing and bolt. If the heads are likely to shear off, I'm thinking of running it to my favorite import shop and having them replace them. My tool collection is just too amateurish to go at this effectively (based on experience with my rear control arm bolts), and I sure don't like the tight space under which I must work for these ones. The front lower outboard control arm bolts came off easily. This contrasts with the rear lower control arms, where the inbds came off pretty easily, while I sheared off the heads of the outboard ones. Update on my other suspension renovation efforts: Team Honda (= cheapesthondaparts.com) in Colorado came through, though it might be because I called them twice in eight days to see why my order wasn't being tracked online per their web site's description. I installed their brand new front suspension springs and stabilizer bar links and bushings yesterday. The Harbor Freight Spring Compressor tool gets easier to use every time, as I learn its idiosyncrasies. The old springs, when relaxed, were a little longer than the new ones (relaxed) by about one-quarter inch. OTOH, the new springs raised the car's height around 1/2-inch. The car is still not level. I continue to think it's a bushing problem. Today's effort was more, slow progress towards possibly changing the bushings out. If I can get over the control arm bolt hurdle, next I'll purchase the ball joint separator tool previously discussed, separate the joints, and inspect. Oh, discovered a badly torn boot where the gear shift rod beneath the car meets the transaxle housing. Doesn't look too bad to replace. Nor does it seem too critical.
