balance shaft
The balance shaft is put in these engines for harmonics at idle to make up for a lack of room for larger weights on the crankshaft no difference in any other rpm range than idle u can take the shaft out and this engine will run fine in any rpm range but idle , many 2004 and 2005 models had balance shaft tensioner failures in high mile apps and these things shake like crazy at idle and run perfect at all other rpm ranges.
