I have recently picked up a Mark 2 Golf 1.6L N/A Diesel. It was old man driven its whole life all highway km's. I recently installed a set of coilovers since the stock suspension was old and falling apart anyways, the rest of the car is entirely oem. I'm aware the front is adjustable at an alignment shop but my concern is the rear inner tire wear.
Looking through past receipts from shops I have noticed rear inner tire wear noted that the previous own did not address years ago and its now showing on the current set of tires that are on it. This was noted long before I swapped the suspension out or I even owned the car - Is this a sign of bad/bent rear stub axles? Wheel bearings etc? Or am I dealing with a bent rear beam. When I had the wheel off the rear drum area on both sides definitely looks dated so I'm hoping a refresh could straighten this out but any help would be appreciated!
There isn't any adjustment on the rear axle. I guess checking the rear wheel bearings aren't loose (but wouldn't account for just inner wear) followed by having 4 wheel alignment. The latter should highlight what isn't in spec. You don't want to randomly swap parts out without knowing the cause.
Like Andy says, I'd get it to a sensible tyre place for a 4 wheel alignment.
While there's no adjustment in the rear, you can adjust the fronts to allow for the rear.
If they give you some crazy figures on the rear, then it's time to go fault finding
