My bmr control arms are starting to make a crunching noise when the suspension is really flexing on them, I know this isnt much to go on but does anyone see anything wrong with these pictures. its also getting cold here(below freezing) and this is my first winter with these bushings so i dont know if they tend to get louder in cold weather or what, any help is appreciated.

i am assuming those are a urethane bushing? if so they do tend to squeek a little but usually putting a decent grease in them fixes that

 

They have zerk fittings. Have you greased them?

 

They looked greased so that's not the issue. What I see is that they may not be torqued down enough. Polyurethane can be impacted by temperature more than rubber can. Meaning that it will expand and contract depending on the temperature. In the first pic, it almost looks like you have a gap between the bushing and the surface it's supposed to rest agains.

I say get under there and Torque them down some more. The crunching is probably the play between the bushing and the mounting point.

 

thanks guys, but earlier today i greased them with the bmr lube and retorqued them to spec. bmr told me the urathane bushings get like this over the winter, but im wondering if something is scraping somewhere even though it is more of a hard urethane vs metal sound

 

Nature of the beast. Im fighting with a bushing squeek in my car now, I hate it, but its cold and thats what happens

 

I'd rather heave squeaking than a buttload of deflection in my suspension, but that's just me.

 

yeah i dont mind the noise i just hope its not a sign of problems to come. it definately feels fine
