PaulaJ Posted October 24, 2018 Share Posted October 24, 2018 My husband&I are recent owners of '86 Toyota Sunland Motorhome, we've replaced old shocks with Belstein shocks but it still doesn't help with smooth ride, every lil bump we hit, makes a big thump sound in back end. Also, husband checked muffler which was making a rattling sound, needs a new one & he's wondering whether he should have catalytic converter replaced also. Any suggestions would be appreciated.

WME Posted October 24, 2018 Share Posted October 24, 2018 New shocks and bushings, check good stuff. Have you looked at the bushings in the rear springs?? 30 year old rubber bushings are usually junk, they will let the rear spring actually move and not flex as they are supposed to. Mid level mech skills need to replace them. New OEM type will be better than what you have, best is the poly bushings that the off roaders use.

Homer Posted October 24, 2018 Share Posted October 24, 2018 (edited) I don't think you have to replace the catalytic unless it's bad because they either work or don't. Very expensive too Edited October 24, 2018 by Homer Quote Link to comment Share on other sites More sharing options...

Very expensive too They do degrade with time and heat and will eventually crumble apart blocking the entire exhaust system causing all kinds of fun issues. If it’s working fine you can continue using it. If it fails it’s easy enough to replace at a later time by a muffler shop. Quote Link to comment Share on other sites More sharing options...
