Just bought this truck and really like it for the most part. It just crossed 81000 miles and seems to have no major issues. A few things do concern me though. I have noted over the past week that on startups after several hours sitting, it gives off a shot of purple smoke. Only for the first second and then immediately clears up. Oil levels seems fine so I am confused. Also, the intermittent wipers only have one speed selection which is a really long delay. Slow and fast speed seem to be ok but no matter where I select the delay for intermittent I get only the one delay choice. I know these trucks need new wheel bearings about 70,000-100,000 miles, I suspect that this one does too but it is not the typical hum of a bad bearing, it is more of a rhythmic thumping that is faint and most notable when decelerating and cornering to the right.
If anyone has and insight or any other issues I might want to be made aware of it would be greatly appreciated. Thanks

Hello, I'm new here too, and also just bought a used Burb ( 2007) to replace the 2005 that just got wrecked in an accident.
First thought about the "thumping" was a CV joint? Are the boots in good shape? Not split etc..?
