Hi all, wonder if anyone has attempted to change the rear tie rods using Craig’s modification? Both of mine have had advisories on the MOT.
Thanks

Yes, did my 4200 back in 2014 and have two sets on the way to me at the moment, one set for the GS as MOT due next week and one tie rod has gone, the other set are for Urby, I'll be doing these for him soon.

Incidentally I make replacement sockets for the inboard end as getting them off the wishbones and or the old tie rods are a total bar steward!

Trick is to be prepared, DON'T do it on axle stands it is not worth killing yourself over! Get it on a post lift. DON'T EVER be tempted to follow the advice of some to 'lower the car on the spanner (on the ground), to undo the inner end!!!!'

As I say, prepare properly, measure known points on the wishbone and the stud end on the outer end so you can assemble to roughly the correct location and take it straight to a good laser alignment to get ALL the geo done, you will thank yourself to for the transformation it makes!

My GS is currently with Emblem and during a full geometry and wheel alignment check they noticed that one of my rear tie rods was seized... is this a common issue?

Did mine on the 4200 a coupe of years ago, on axle stands on the drive, considering how much rust there was generally under the car, wasn't too bad a job at all, gave a good soaking of WD40 24hrs before hand, and cut through old ones with a grinder, then removed wishbone and placed in a vice, piece of p*** as they say,considering the horror stories must have been lucky;)

I would say yes, very common.

My tierod sockets were extremely tight, but a suitable amount of swearing got them undone. I have to admit, I didn’t see anything wrong with the original type bearing, It’s a quality SKF part and you could buy enough for 5 changes for the price of the upgrade kit. GE15C is the part number as I recall.

I’m led to believe that on mine it was completely jammed. After several efforts, in the end Myles had to cut off the seized tie rod so he could use an air powered impact gun to release the adjuster from the arm. He then had a tie rod in his magic tool box which he fitted a new rose joint to and fitted to the car.

Bish Bosh, job done, and the car is now fully 4 wheel aligned...

I have a 2 post lift, when you say you made new sockets did you fabricate them from scratch?

And I'm not sure if those kits are road legal either, you'd most likely have to inform your insurance!

I commissioned a set of 40 back in 2014, they have all gone so I'm ordering another 20 from a local engineer, should have them Friday and just need to get them BZP treated to match OEM. The advantage of new sockets means as has been indicated above, you can (after measuring twice!) cut the old tie rod and use a monster nut gun to drive the whole socket out with the end of the tie rod still in it thereby reducing the break free forces needed by at least half. I sell them at cost and will know what this is when they are ready.

Excuse my ignorance... Are the terms tie rod and drop link interchangeable? I thought tie rods were a steering component and drop links connect the ARB the control arms... Or... ???

When I did mine they were a real pain, needed a lot of heat and soaking in penetrating fluid for days as had the arms off the car.
Replaced with the standard skf bearings and been good for 3 years since.

Just put pic in last post, adjustable tie rods are on rear lower wishbones, can adjust the toe in/out.

Yes - drop links just link the roll bars to the suspension arms

Not interchangeable, drop links are the vertical links to the anti-roll bars front and back. Tie rods control the toe in/out on the rear setup, effectively adjusting like the tie rod ends on the steering although ti is actually an angular adjustment on two planes in this case.
