HELP! Rear end hissing/ whistle noise & other issues - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

jamrome918 · 07-17-2012, 11:20 AM

So I drive a 91 coupe 240sx , I've encountered problems left & right with my baby which is kinda fun to solve. Anyways when I'm driving I hear this whistle/hissing coming from my back area. I know it's not coming from my fan clutc etc, because my whole cooling system is new now. But anyways it's a high pitch whistle or hissing, it only happens when I'm in gear & the sound cuts off when I put it in neutral. ( I have open dif) If that helps out.

Also I have another issue with my rear end. When I'm in neutral and my car rolls back it sounds like my bac right tire locks up or grinds on something. Sounds like "graaaaggghhhhh" Ive read that it may be my wheel bearing, caliper , & sub frame bushing.

Last but not lease! My back right tire seems to skip when i accelerate on 1 & 2 gear. And when i turn left. Its like that same sound "graaaagraaagrraaa" but wuieter . But yeahI just want to clarify things from people who may have had the same issues in the past. Any help would come to great help & would be appreciated. Please & thank you!

Your diff has evoled into a SNAKE! Hire "turtle man" for some live action snake wrangling.

i beleive its your rear wheel hub bearing that might be making that noise , i had one go out on s14 and it would make a grinding noise when under load and then start like a high pitch whistle after a while
no turtle man needed
