Sanity Check: Drivetrain Load-Up Noise/Clunk from Park > Drive

2017 GX460, 68k miles. Purchased at 50k after dealer service.

About 4mo ago I started feeling (or just started noticing) a ‘clunk’ going from Park > Drive. Felt like the driveline was ‘loading up’.

About 3mo ago I took the vehicle out of Park into Drive, pulled my foot off the brake and at the same the ‘clunk’ happened I gave it a bit of throttle (driving forward out of a parking spot). I felt a shutter and the Traction Control light popped on for a split second. Stopped, gave gas, all well.

2mo ago I completed the following:
- Greased the driveline (definitely needed it, dealer clearly did not do it)
- Transmission drain/fill plus new strainer and gasket
- Diff fluid drain/fill (both)
- Transfer Case drain/fill
- Did not find slop/play in the driveshafts

The feeling is much less now, but I still feel the car almost push forward slightly, like the driveline is loading up/giving up slack when I shift into Drive. I ‘feel it more’ when the car has been sitting, like in the morning. This makes me think the driveline releases slack over time and the transmission applies torque when I shift, removing the slack.

  1. Is this normal? V8, heavy duty transmission, transfer case, two drive shafts, and two diffs afterall.
  2. If not normal, could it be I need to add more grease to the driveline after the initial grease made it across the components? Yoke going bad and needs new driveshafts?

1993 245 Left Tailgate Wiring Harness

The last part I need is the left tailgate wiring harness. I have an OEM on back order with IPD. To speed things up I am considering cancelling and going with Swedish Car Parts or MTC.

Swedish Car Parts: They told me their factory in Estonia makes them ‘to factory specifications’.

MTC: uses larger/less pliable copper strands than OEM and may have insulation degradation issues.

Perspectives appreciated.

Third Brake Light Assembly (1993 245)

I need to find a full third brake light assembly for my 1993 245. I found two options on VPAutoparts but unsure if I also need some sort of cover.

Option 1: Aftermarket Replacement looks like a full direct replacement but what I think is the clip at the bottom goes an odd direction. Anything I would need on top of this?

Option 2: OE Replacement looks like I need the Taillight Housing, Red plate, and seal. Anything I am missing like an additional cover?

Long Time Listener, First Time Caller - 1993 245

Excited to share my purchase today. Bought her from a lovely woman who absolutely adored her and I look forward to getting her into great condition for many more odometers to come.

Dropped her off at a Volvo shop this afternoon to have some needed immediate work done. Looking forward to fixing a bit of rust, cleaning her up, finding an OEM front lip, figuring out why the radio doesn’t work, and eventually spending twice her value on a paint job.

One question: DL or GL? Has an 8 in the right part of the VIN, but has a clock, not a Tach. Leather (I think). Unsure if the wheels are original.

What should I consider doing immediately to ensure she’s in excellent base condition (Stage 0)? What are the follow on suggestions for improving her?

Been researching for a few years and excited to dive in.

Front Diff Fluid Change: How much is too much material on the magnet?

2017 GX460 66,800 miles

Front differential drain plug. Cleaned the magnet and about 1/8tsp or so material came off. How much is too much material on the magnet?
