Iâ€™m looking to replace the rear axle damper shock (5th shock) with either OEM or an equivalent performing unit. Iâ€™ve searched here several times, on google, eBay and all the local auto parts stores online with no luck. The OEM part # is 05290831AA. The one in my truck had been leaking so I think itâ€™s time to replace. Iâ€™d be happy with a stock setup as Iâ€™ve already scoped out whatâ€™s available from our vendors and really donâ€™t think Iâ€™ll have a need to go that far unless the cost of a stock unit is so high that I might as well spring for it. I donâ€™t plan on taking it to the track but I do like monitoring performance with my G-timer after a repair or upgrade. Itâ€™s also not my DD and usually only driven during fair weather. Any help would be appreciated!
