Rear Output Shaft Bushing, 246 261HD 263HD | 1999-2007
This is the replacement rear output shaft bushing for the NP246, 261HD and 263HD transfer cases used in 1999-2007 GM gas trucks and SUVs. It is item A12 in the exploded view. The bushing supports the rear output shaft and rear driveshaft yoke in the rear of the case. When it wears, the yoke can move around, which tears up the rear output seal and causes leaks. A worn-out bushing very commonly means the case half has been damaged as well and should be replaced. It will NOT fit the 261XHD or 263XHD.

Frequently Asked Questions
Will this fit my Duramax?
No. Duramax trucks use the 261XHD or 263XHD transfer case, and this bushing will not fit XHD cases.
Do I need to replace the case half too?
Often, yes. It's very common that a worn-out bushing means the case half has been damaged. Inspect the bore in the rear case half before reusing it.
How do I know which transfer case I have?
Check the ID tag on the rear half of the case. It will read 246, 261HD, 263HD, 261XHD or 263XHD.
