KenRX350 Posted August 4, 2010 Posted August 4, 2010 My 2010 RX350 owners manual states that every 5000 miles the drive shaft bolts must be re-torqued. I am sure thats not a cheap service. (1) What the heck is that for? Never heard of such a thing. My old car went 200,000 miles and I never touched the driveshaft. Now I have to torque bolts every 5000 miles on a $45000 vehicle??? (2) Can I do this myself? Are there instrctions / diagram someweher for this? Thanks! Ken in Md

Ask your customer rep why that is needed. Retorquing is not difficult. But you have to lift the car and have a torque wrench.
KenRX350 Posted August 5, 2010 Author Posted August 5, 2010 My rep said they visually check it out, dont actually touch it. I said that's not what the maintenance log says, and he basically said it's outdated and not to pay attention to that item.
LeodLion Posted August 5, 2010 Posted August 5, 2010 Some of these bolts have a little dab of paint at the bolt head and into the thread. I suppose one of its use is to be able to visually check if the bolt move.
Sajack Posted April 14, 2023 Posted April 14, 2023 My ‘02 LS430 manual says the same thing. After 20 years of service I asked a mechanic about this. He said it’s for areas that have really bad roads in which the car gets rough service. He checkd mine and said none of them were out of spec.
