Tall Guy Posted June 4, 2010 Share Posted June 4, 2010 I have a 2003 LS 430 with about 125K miles. Over the past 2 months the noise in the cabin seems to be significantly increased. Its just a general engine hum/whine and i don't think there are any issues with the car just wondering if there is something that used to be dampening sound or insulating sound from the cabin that could be wearing out/getting old or perhaps broke in some way? Thanks. Quote Link to comment Share on other sites More sharing options...
etex Posted June 4, 2010 Share Posted June 4, 2010 Are you sure it's from the engine? May be tire noise... How many miles on your tires? Quote Link to comment Share on other sites More sharing options...

Tall Guy Posted June 5, 2010 Author Share Posted June 5, 2010 I'm not sure, it could be tire noise I guess, about 20,000 miles on the tires although they are my snow tires which I still need to switch out. I'd say I'm 90 percent that its engine noise rather than tires. Quote Link to comment Share on other sites More sharing options...

dpellet Posted June 20, 2010 Share Posted June 20, 2010 Engine and trans mounts or the exhaust. Mechanic says it is a rear wheel bearing going, is that plausible? Yes, very plausible. Do both rears if one is bad. Quote Link to comment Share on other sites More sharing options...
ggemigniani Posted June 21, 2010 Share Posted June 21, 2010 Highly unlikely to be rear wheel bearings. Get a second opinion. Rear wheel bearings normally last the life of the car (unless the owner is they type that does burnouts, corners extremely aggressively or lets the differential lube get low or contaminated with water by driving through or parking on flooded streets.

VBdenny Posted June 22, 2010 Share Posted June 22, 2010 I'll stand in agreement with gg's opinion. Take the snow tires off before you decide anything. Snow tires really heat up in the summer and the were not designed for high heat roads. I'll bet those things are coming apart and that is causing the noise. When I have the snow tires on my ES330, they are quite loud. Don't let some shade tree mechanic touch your wheel bearings. Quote Link to comment Share on other sites More sharing options...
