Have had a few that bent trying to free off... One was on the ramp at WIM.Even if you don't refresh the rear suspension, you would be well advised to replace the rear track rods as they have a nasty habit of seizing solid.I only ever bothered if they needed adjusting, and heat couldn't free them. Obviously when fitting new, a good coating of (proper) coppaslip on the threads tends to prevent further reoccurance.
Without seeing or knowing the car or it's history the advice would be to replace them.
