XK150 Suspension

Hello to all, I have been enjoying my 150 this summer, driving it to work when ever I can. It has performed well but still has some definite draw backs from modern automobiles. Specifically the ride is hard. I know that 50's british sport cars were suppose to stiff in the suspension and only a wimp would complain about it. Maybe I am getting old but this car is beyond stiff and is uncomfortably hard riding. Even the slightest bump will produce a spine jarring effect in the seat. I replaced the shock absorbers, hoping that would help, but it did not. Do the rear leaf springs ever lose their ability to dampen out the potholes, bumps and other road imperfections that we have to deal with? Is there anything I can do other than drive my xj6 instead of my 150? - Best regards, Don Sime

Don, I don't think the 150 should ride as hard as you described. The rear springs can definitely sag with age, and I suggest you find a good old fashioned suspension place that will remove and reset them, and who can also check the height of the car at the front with the torsion bars. It is also not uncommon for a leaf to break in the rear springs (or is that only on some of our poor Aussie roads?!). Check all the bushes too. Metal to metal does not help much. By the way, Sydney Concours tomorrow (Sunday) and it's been raining (Saturday). Hoping for sunshine and about 25 XKs down by the harbour. - Regards, John Elmgreen

Don, Look at your rear springs to see if they have collapsed. I had to replace the ones on my XK120 a few years back because of this. Check the clearance between the bump stop on the frame and the axle. You should have several inches of clearance. Do the same in the front. The lower A-arm should not be riding on the bump-stop. If it is or is close, the height can be easily adjusted per the shop manual. I put a set of Woodhead shocks on my XK140 and have liked the ride. - Cleo Bay, XK120, XK140
