It had a noisy bearing.

Normally I would agree completely. The issue I have is that this particular balance unit has a sordid history. When my car engine was released the Volvo VIDA repair manual said this about the balance shaft: "To ensure correct backlash, the balance shaft housing is shimmed to the engine block at the assembly plant. If the balance shaft housing must be removed, the entire engine block must be replaced." (My emphasis.) Clearly Volvo considered this a very reliable part. It wasn't. They failed often. So they had to come up with a fix for the balance unit, and also define a field replacement procedure that was reliable. It was not until early 2019 (6 years after introduction) that they had manufactured parts with a decent fix. The field replacement procedure (TJ 32958.5.0) had a serious caveat: "It's extremely important to adjust the new balance shaft with the correct tools according to the instructions otherwise the sound may occur again in a short mileage (sic)." (Their emphasis). So I am very leery that this is a tenuous fix, and it may quickly fail again. Given all the problems with this car I am looking at all options. If there are any Volvo tech's around that can comment on this repair procedure (is it now reliable?) I would appreciate it. Thanks again. |
