Need Help With Fishtailing

[lexs400]

my 90 LS has developed a weird phenomena.

at highway speeds the rear literally feels that it's going to give out when changing lanes. kind of like a boat. i believe it's called fishtailing...

what bushing/part would i need to replace to correct this ?

thanks.

More than likely the axle carrier bushings, they're at the end of the long rod that runs front to back from the chassis to the rear upright. Mine are shot too, just haven't had a nice day to replace them yet. You can buy urethane replacements like the Adus 505 bushings, or the dealer sells a repair kit with new rubber ones. There's a writeup somewhere on lexls.com.

Something else you can check is that the rear sway bar is secure. Check the brackets/bolts and bushings.
