quick question. solid subframe bushing

[shalezzz]

So i installed solid subframe bushing and a new 1 piece driveshaft on my 90 hatch. and now when ever i let of the gas and start to slow i hear like a noise hard to describe sounds similar to a flat tire but louder and cant hear it when accelerating or hard breaking.i figured it was my dif cause a good bit of gear oil leaked out of the breather when i had the subframe out

i also had a somewhat frozen caliper.

or im not sure if my drive shaft isnt balanced properly.

or is that just what happens when you have solid subframe bushings

i tried the easiest method my adding gear oil but the plug is frozen and my impact cant break it free any ideas about what it could be

Well you should always try to unscrew the fill hole first then the drain hole so you don't get screwed.

Put your back into it and get that fill hole out so you can add some oil and see if the problem goes away.

solid mounts make more noise, your gonna start to hear things that scare you hahaha

i have subframe collars that arnt quite as bad as solids but still transfer alot of noise and i just changed clutch, pressure plate, transmission, and have a stiffer transmission mount

im hearing all kinds of stuff!!

like around 2500 to 2000 a CRAZY loud like almost whining noise when the engine is decelerating itself and crazy vibrations at 1000rpm

i need those soild mountsfor my j30 i hear a little clunk in my diff when accelerating lol

everything seems to be working fine, i had never replaced any of this stuff before so im still a little worried about the swap cause of that noise as well
