Fishcca Posted July 4, 2004 Share Posted July 4, 2004 Hello all- My LX 450 with 75000 miles, makes a rattling noise these days. It only does this when I start movement from a standstill. After a few miles an hour it stops. Although I can not hear it very well, I think that it is doing the same thing after I am coasting for a bit and then redepress the gas pedal. Any one had a similar problem before. It took it to the dealership and they didn't find anything. I have the feeling that my mechanic was a newbee. I also replaced (myself) a head lamp for 9 dollars that he wanted to charge me 90 to replace.... I will only take it to Sewell from now on... Thanks for your ideas...

dougjohn Posted July 6, 2004 Share Posted July 6, 2004 More info would be helpful Fish. Where's the noise coming from? Front, rear, left side, right side? Can you get a friend to stand outside and help pinpoint the location of the rattle? Quote Link to comment Share on other sites More sharing options...
tcshell Posted July 9, 2004 Share Posted July 9, 2004 I had the same problem. A bolt had fallen on to the engine brush guard. This cause a noise at a low speed. I could not hear the noise unless the LX was moving! I took a RUBBER hammer and tapped on the brush guard until the bolt was found. Turns out there were two bolts. I hope this helps. Shelly ps. I still am looking there the bolts go:) Quote Link to comment Share on other sites More sharing options...
ellieoh Posted August 14, 2004 Share Posted August 14, 2004 The vibration is probably the heat shield on the silencer or catholic ;-)converter under the passenger side, get a large hose clamp and secure heat shield with clamp.

dengman Posted December 27, 2004 Share Posted December 27, 2004 I currently have the same problem with my 97LX and was told at the dealership that it is, in fact, the heat shield. I temporarily fixed the problem with a coat hanger. At the dealership, the tech removed the coat hanger and tightened the shield, but it is now worse than when it had the hanger. Now I am looking for a more permanent solution. The cost for replacing the heat shield is about $350 + labor. A technician at the Lexus dealership said that removing this heat shield is another option. Does anyone have a view on this much less expensive alternative?

lextildeath Posted December 27, 2004 Share Posted December 27, 2004 Could possibly be the throttle tubes came disconnected and is just held flush to eachother. Check that and make sure of it. Stick em in and then tighten the bolts. It happened to me in my ES 300. Quote Link to comment Share on other sites More sharing options...
dougjohn2 Posted December 28, 2004 Share Posted December 28, 2004 The heat shields do get loose and will rattle after a while. They can be removed, but the passenger floor board might get a little hotter. Nothing too serious, but it would be noticable. I wouldn't get new ones...unless or until you replace your cats.
