top mount atop the the spring the bearing fits into the mount. Bearing can become worn, normally in the straight ahead position. So as you turn, it clunks. The grease can escape also, giving a grumbling noise and rough feel to the steering.
top mounts at the bottom of the image prior to fitting. -------------------------------------------- Suspension as mentioned, best practice is replaced in pairs. Below are the rear struts from my car. It showed no obvious signs of any issue, and handled remarkably well, passed MOT 11 month prior. I never felt the need to do the 'bounce' test. But imagine if the left one showed weeping just before the MOT. You replace it, the right one, whilst looking corroded, doesnt show signs of weeping (it wouldnt, I guess lol). So you just replace the left one

The shock mountings( top mounts) have a compliant bearing which allows the joint to move, but restricts the amount of noise and vibration transmitted through to the chassis.
When they have failed and been removed they tend to fall apart When the steering is turned left to right or right to left you will hear a clonk, it’s easy with a assistant to establish worn top mounts as one can turn the wheel while the other feels the spring, they will notice a twang effect from the coil spring.

Thanks, i have rumbling from the front susp, and its not arb drop links or bottom arm balljoints or bushes, so I suspect top mounts. So do i order top mounts or bearings, or both? I plan on getting new shocks, so getting all done together one sunny winters day.
I recal dmgrs stating that the bearings he sells also fit 25s, but I've had 25 struts in bits, and never seen a bearing worn, or had this rumbling rattle either? |

Posts crossed, thanks for replying. I don't have the clonk on applying lock, just a rumble/rattle on rough roads (most around here).
So, new mounts and bearings? |

I have in the past recycled used bearings from a 200 to replace ones on a 75, and they were like new Brian |

Broken Coil springs seems to be almost an epidemic these days, I have lost count of the amount I have replaced.
I will say you rarely see one that has broken that still has paint on it, usually they are rusted or at least in the area where they have broken. Probably a combination of fatigue, rust and age. If you keep bending any piece of metal for long enough it will usually break. The fact that most motor factors keep all the common ones in stock tells you how bad it is, they don't even carry spark plugs for some cars yet they will have new springs on the shelf for the same vehicle.

They’re at that age now where springs breaking are all too common because of stress, rust etc. We will see plenty of this over the coming few years. I just hope people don’t scrap them because of it as springs are still easily obtainable and it’s not the biggest or expensive job...

Seeing the way that some people "monster" kerbs and speed bumps, it's hardly surprising that, along with pothole "clouts" and the reduced weight/structure of modern car springs, so many fail. I've replaced many a leaf spring in the past but mostly on HGV's that had to work hard for a living! (Still have the broken bone in my foot from dropping one off the side of the ramp - Ouch!)

Couldn't move it, couldn't get a jack under it, so phoned my usual garage to ask them to recover it and sort it out in the warm & dry. They said they'd be over in a few days, fine by me as I had other vehicles to use. Thought it odd a couple of days later that the Rover appeared to have regained a more normal attitude. Checked the other side, to find another bust spring and another new Michelin written off, with not so much as an attempt to move the car: Both front springs had failed in the space of 3 days or so. Fitted tyre protectors after that!
