Recently, there was a gear oil leak in my corolla 2000 xl. So, had the ff. done :
1. transmission oil seals (left and right) replaced
2. Changed gear oil to Shell spirax G SAE 90. Saw them fill to the max.
3. I also opted to replace the inner cv boot (left and right) and grease repacking. Saw that they put 1 small bottle of grease (estimate about 100ml) per boot.
4. Replaced fan belts for alternator and compressor.
After the repair, I felt that my ride feels rougher specially during high rpms. At idle, nothing seems to have changed.
My question is .. Does the repairs have anything to do with the rougher ride ? Or maybe I'm just noticing something that was already there before ?
