My wife's 2003 L300,3.0 litre V6, just over 80k, near mint condition has stiff, groaning steering. My mechanic diagnosed steering shaft coupler is rusted and seizing up. Still drivable, but getting stiffer and noisier. Lubing the part is ineffective! Dealers, local parts suppliers, even auto wreckers all have no luck finding new or used part. Both Canadian and U.S parts suppliers have given me Darman part#425-101 for reference, but no luck locating a part yet. Any help is greatly appreciated.
