A shop here botched swapping the u joints out of my propeller shaft. Its a toyota prop shaft with a center bearing, with staked on joints. So the shop removed the stakes and replaced the u joints with zerk type. Unfortunately since this is a stake on type, the inner surface of the yokes are not flat, so installing a circlip type u joint is out of the question. They installed the zerk u joint and welded a washer on the outside caps to prevent the u joint from shifting. But problem is I got a vibration over 60mph, which leads me to beleive they couldnt center the u joints and yokes properly. I got myself a one peice, and it also exhibits a vibration over 70mph. The problem is no one can balance a driveshaft over 1500rpm in my country.
So I bought a used untouched prop shaft from japan with the original U joints intact from factory.
Problem is one of the joint is abit stiff, so i was thinking of prying the rubber seals at 4 location on each seal and injecting grease with a needle head on a grease gun. Has anyone tried this before ?
Dont ask me to get a shop to change out the u joints, it's out of the question. Leaving the original u joints in is the only way I can ensure the yokes are perfectly centered. It sucks being in a 3rd world country.
