Hello everyone,
I recently purchased a used 2008 LC (US) and am very happy with this vehicle. During my research, I pulled all the Technical Service Bulletins (TSBs) to make sure I had any issues covered/understood. So here's my situation: I have a minor steering wheel vibration between 1700-2100 RPM, exactly as described in TSB 0071-09. My LC has 49,000 miles and is over 5 years old, so I'm out of warranty and would have to purchase the repair parts out of pocket. The repair consists of replacing the transfer case (around $2500 USD) and some other more minor parts, such as adding insulating padding. The level of vibration is not severe, though very unexpected for a vehicle of this level of quality. I'm not to the point of replacing the transfer case yet because I don't think the benefit is worth the cost. Out of curiosity, I looked up the TSBs for the LX570, and it has the exact same symptoms...with a slightly different repair procedure. For the LX, they also replace the transfer case and add the insulating materials, but ALSO they replace all the front differential mounts with revised parts, and add a dynamic damper to the front diff. I thought this was very interesting, since the front diff, transfer case, engine, and front chassis is nearly identical between the LX and LC. So my question is: Are the components recommended to be replaced on the LX due to a different standard for acceptable vibration within Toyota, with the LX being held to a higher standard? Or are there design differences between the LX and LC that prevent the LC from being able to accept the additional dynamic damper and updated front diff mounts?? I could get all the parts for the front diff mounts and dynamic damper for around $300, which I am considering trying just to see if it significantly reduces my vibration issue (I don't expect a complete fix without transfer case replacement). Has anybody had this repair procedure done on their LC or LX? Anybody else experiencing this vibration? Does anyone have enough experience with both the LX and LC to theorize on why they would add the damper to the LX but not the LC? Thank you so much for any advice! I will attach screenshots from each TSB to show the difference in repair parts.
