During my last visit to the Jaguar Forums, I came across this helpful post. The owner of a 1997 Jaguar XJ6 L complained that the right side of his car rode lower than the left. After replacing the front shocks, nothing changed. The right side was still about 1/4″ lower than the left side.
Why would a Jaguar XJ6 lean a little lower on one side?
Several people came up with suggestions, but Don B. offered the most probable solution to the problem.
“It is not unheard of for springs to sag with age, but the most common cause of sagging ride height is deterioration of the big foam rubber ‘donut’ spring isolator bushes, Part 5 in the diagram below. Since the bushes are more than an inch thick, there is a lot of ride height to be lost as they lose their resilience and compress with age.”
Hunting down a problem is the hardest part of working on cars — especially a Jaguar XJ6 (X300). If it had been my problem, I probably would have bought new springs, shock absorbers, tires, and then sold the car to relieve my frustration before realizing what the real problem was. That’s the beauty of visiting the forum when a problem arises.
