Delphi applies OE safety technology and dimensional analysis to help match the original part’s fit and material characteristics, which is important when replacing a worn bushing in the suspension knuckle assembly. The TD1401W part number is used for this application across the listed fitments, and TD1401W also cross-references Dorman - OE Solutions 540-134 for the same application.\u003c\/p\u003e\u003cp\u003eDelphi validates this bushing through temperature cycling and corrosion exposure to verify performance under demanding conditions. For buyers searching for a Land Rover LR4 rear upper suspension knuckle bushing, a Range Rover Sport rear upper bushing, or an LR3 rear upper suspension bushing, TD1401W provides a direct replacement option aligned to OE-style specifications.\u003c\/p\u003e\u003ch2\u003eCommon Uses\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacing a worn or deteriorated suspension knuckle bushing\u003c\/li\u003e\n\u003cli\u003eRestoring suspension joint stability and alignment consistency\u003c\/li\u003e\n\u003cli\u003eAddressing noise or looseness from the rear upper suspension area\u003c\/li\u003e\n\u003cli\u003eCorrecting fitment issues caused by dimensional wear in the original bushing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\u003cp\u003eInstall in the rear upper suspension knuckle position only for the listed applications.
