Too low = blown axles??

[Def]

If you keep blowing axles up, raise your car. It's got to be super ricer low.

Raising your rear subframe up with bushings also helps this slightly, but won't correct ricer ride height.

I would highly recommend these ^^ & the PBM rear s chassis drop knuckles, together they will correct alot of those roll center problems. I've installed them on a buddys car before for these exact reasons you're having and am installing them on my own car very soon. They're a bit pricing but Quality parts > a Quanity of used axles in my opinion

Yeah my mistake. I was thinking of this when I made that post: DIF 10086 Steering Rack Linkage Bushing 1989-1994 Nissan 240sx S13

Keep us posted as if they are reasonable in price I'm sure people will be interested. Especially since there doesn't seem to be a lot of reputable companies making these pieces here.

I think TheRealSy90 hit it on the head there. Your subfame raisers had a lot to do with it as it changes the geometry of the suspension in such a way as to make the LCA's flat (or something like that). I read about it in the roll center suspension post (600+pages). Also adding spacers on top of that will help and that's just what I've gathered from reading this thread.

To answer your question though, they go bad because the boots are not made to be at such an extreme angle when lowered so aggressively. Someone who posted the link to the OReily brand suggested that the new boots were made to correct this but at the end of the day, why not do it right the first time.

Was concerned about this myself before even driving my car. S13, Z32 NA Diff, J30 5-Bolt axles. The driver side shaft boot is at a creepy angle and the boot has an "underfold" in it. On jackstands btw.
