Control arm issues.

[John97Tdi]

Hi,I planned this morning to change both control arms and balljoints on my '06 XC70.I'd been spraying plus gas on the various nuts and bolts over the past week so,having watched SiRobb change a control arm in 20 mins(while holding a camera!),hoped I would get everything done in 4 hours or so, ha!
Every nut and bolt had seized and could only be loosened by a breaker bar and then winding back and forth until they came loose so it took the best part of 4 hours just to get to the point where I could take off a control arm(passenger side).
By this time I'd decided to leave the balljoints for another day so attempted to fit the new control arm. It went on fairly easily but when it came to locating the balljoint,no matter how I tightened the ratchet strap it would not slip into place and seemed to be about an inch adrift. It didn't help when the ratchet strap stopped ratcheting but even with brute strength and ignorance, and a long bar,I could lever the control arm low enough but the balljoint would not seat.
I suspect that,despite being careful, the driveshaft has come apart and added extra distance hence the problem.
I can't be the first person this has happened to so how do I check and if needed relocate/rebuild the shaft?
Before anyone asks I compared the control arms side by side and they matched and even tried refitting the old arm but the problem is still there.
Any advice welcome but it may be a few days before I can have another go at this since I work on the car outside and the weather is changing for the worse.

Cheers

John
