09 Is250 W/5000 Miles Thumping Noise.

[coastgardsman]

Hello, new guy here...Ran across this forum by accident and its been really helpful and glad i joined it. This may help some of you who have the same problem i had with their cars. I bought my wife a 09 is250 with less than 5000 miles on it. The first couple of days having it we would hear a thumping noise every time we would go over a bump or turn in a parking lot. It traveled from behind the moon roof down to the front pass side.Long story short, i took it to lexus and they had it for 2 weeks, replaced the struts, shocks etc.. it ended up being the sun roof trac..so they replaced that and its like new now.

Also would like some of your veterans advice here in HID lights. What a good brand to go with to convert my reg to the hid lights. I see lots of them on ebay and im just afraid of buying a set and them not turning on at times. Thanks
