Symptoms
A loud bang from the front when turning or reversing, wandering steering or clunks over bumps.
The fix, step by step
- Growlerbearnz calls it 'the classic L300 clunk' and lists two usual causes.
- First, the 17 mm nuts holding the rear suspension subframe to the chassis rails work loose, and they should be very tight.
- Second, the anti-roll bar bushes wear.
- Then check the upper and lower ball joints, tie-rod ends, CV play, shock bushes and wishbone bushes.
- To change an upper ball joint, support the van, back the 24 mm castellated nut off a few turns, break the taper, then remove the three bolts on top of the upper arm.
- One member gives the OEM upper joint as MR241623.
- With ball-joint lift spacers, fit a long straight grease nipple.
