[TR] TR4 Investigating replacing the Armstrong lever shocks with telescopic rear shock conversions

[Peter Ryner]

Agree with Randy,
Check the shock mounts.  Had the same problem on my TR3.  Would get noise on bumps and couldn't fine the problem  Finally got loose enough that I could move the shock.  Mount holes were rounded out by then.  ISTR that there are no lock washers on the mount bolts.

Hi Will-

Moss-Europe still shows the kit for the TR2-4 live axle cars.
https://www.moss-europe.co.uk/shop-by-model/triumph/tr2-4a/steering-suspension/rear-suspension/telescopic-conversion-bracket-kits-tr2-4a.html

It seems a bit involved with brackets needed to be welded to the differential axle tubes.


A couple of thoughts on the rattle - I'd check the shock links very carefully as one step.  The rubber inside the link can perish so you can get a rattle even though the link looks ok.  The number one problem I had was the lever shock mounts would come loose and the shock would move a bit creating a noise.  Those bolts are hard to access, some use a socket headed bolt to get better torque on them.

If you are convinced its the shocks, you could test the theory by removing them and driving around for a while - the car will bounce more but if it still rattles it means the shocks weren't the problem.  I had a rattle from the muffler hitting the frame which might be a possibility.

Cheers
Randy

When going over bumps in my TR4 I have quite a rattle from the right rear area of my car.  I have poked around by the axle, and thought I have fixed the problem a couple of times.  I have replaced the springs and refilled the Armstrong shocks.  I have poked around. While looking through my Moss catalog I noticed the kits for replacing the Armstrong shocks with these brackets that you could mount shock absorbers to. But the kits are NLS.  No Longer Supplied.  I was wondering why the kits  were discontinued.  It could have been that they caused damage to the frame, or just didn't work.  I was hoping somebody had any first-hand knowledge or experience on this topic that they could discuss. I wonder if the racing group all have custom and proprietary set ups.
