Hi all! The car is a 1988 1.6D CL, non power steering, LHD.
I did some diagnosing, inner and outer tie rods are fine. the only way i could get it to make that clunking noise was if I violently pushed/pulled either of the front wheels, while holding them at 3 and 9 o'clock. I had my dad look under the car while i shook the wheel, and he said the noise is coming from the steering rack.
No noise or play is present when turning the steering wheel or going over bumps that span across both wheels.
Could this clunking be because of worn pinion bearings? Maybe some rack guides inside the housing? I've had a lot of trouble finding anything about this rack, are there even are bearings to change? While checking the u-joints, i did notice that the pinion has a wobble, meaning, it doesn't stay exactly centered. I checked the preload, and it was already well adjusted.
If anyone has any knowledge about this rack or what else i should check, please leave some in the comments, i'd appreciate it.
