Bouncing rear issue
Hello everyone, hope you are all doing well, I have a problem and I am not sure anymore what the issue might be, so I own a used GX460 and I have just done the major service at a relatives garage, fluid changes at 97,000 km, brake facing, new pads, front bushings have been replaced, rear left suspension had a leak so I replaced it with an OEM part thinking it would fix the bouncing if the rear however it has not done anything at all, the bouncing still occasionally comes and goes after a few minutes and the car just shakes and bounces even over the slightest bumps or roads, the rear left side of the car sags slightly but it is noticeable at certain angles, so now I'm trying to figure it out, (I am getting a reallignment tomorrow) but the only other explanation I could come up with is, the air struts need to be replaced or I need to replace the sway bar in the rear, please if anyone could help me it would be much appreciated, I geniunely don't know where else to ask and was told I'd get an answer here or a solution

You say "rear left suspension had a leak so I replaced it with an OEM part" what was replaced? if it is the shock did you only replace the left rear shock?
Bounce is typically worn shocks, they don't have to show a leak to not dampen, so the problem could just be the right rear shock.

@IanG but that's the thing, also sorry I confused shock absorber with suspension, the shock absorber on the side that was sagging was replaced, however it is still sagging, the right side shock absorber and air strut appear to be fine it was the drivers side that had an issue, however it is still sagging, could to be due to a faulty or old air strut?

Shocks do not support ride height ... they only dampen. Do not understand your "air strut" comment ... the rear suspension on the Luxury model has Air Bags versus Springs as on the Premium model. Maybe you have an Air Bag problem. Air Bags / Springs support ride height ... shocks do not.

Sag as @ASE said, also I would never replace a single shock, especially at that mileage. always replace in pairs
