Front top mount musings ...-gctid3998

Post by TimS » Tue Apr 14, 2015 10:45 am

Hi all,



After being bounced about in the Ranger with it's over-stiff front shocks, I'm getting closer to buying a pair or 'stock' front strut inserts. ;-)



However, whilst checking out the shapes and sizes of the end of the piston rod yesterday I noticed the rubber in the mount was looking a bit tired (not surprising if they are 37+ years old)!











Now, if the rubber bush should fail completely, I don't think any major harm will be done as the top spring cup will just end up against the bottom of the mount.



However, I have changed rubber bushes in the past (often down to an MOT failure) and in many cases, once you have gone past the surface, the rest of the bush is good and intact (and unlikely to ever fail in the real world). I wonder how long they have looked like they do now ... 5, 20 or 30 years? Has anyone ever had one of the std rubber bushes fail?



That said, 'in for a penny' and if I am stripping the front struts out to change the dampers (and possibly the disks), should I replace the top mounts and if so with what?



I know we have discussed the issue with self-centering and the fact that the top of the springs *are* fixed (can't rotate) on my Ranger which isn't how they work on most other cars today and not even all Mk1/2 Escorts from the same era?



I know some here are running a 'bearinged' top mount so they must be ok in use so I wondered which type and from where please?



I think the 'ball joint' type, set in rubber seem to be the best value for money, as seen here:

So, thoughts from the panel please. ;-)



All the best, T i m

Tim,

I like the look of the ones in your link. Kind of wish I'd spotted them before assembling my front struts, Oh well :-?. I re-used what looked to be rather good solid rubber ones and am yet to experience the consequences of that decision :).

Hi Paul and thanks for the reply. ;-)

Yeah, they seem to be the same as in the following link but that gives a bit of the history. ;-)

This is why I ask here before doing anything 'important'. ;-)

Well, hopefully the outcome will be 'perfectly fine', and this is part of why I am often reserved when it comes to these so called improvements.



Ok, after driving cars with power steering the Ranger does feel a bit heavy when parking and making tight turns slowly. However, I've somehow managed to drive it for around 27 years now and don't think it's any different to what it was when we first built it.



So, given that 'new' all rubber top mounts aren't available, we all seem to be guided towards the bearing replacements with an 'advantage' being that they make the steering lighter.



Now, the only thing that still concerens me is that if Ford designed it to work with a basic rubber bush and with springs that wound and unwound as you steered, what happens to the dynamics of all that when you change a key way it works? Altogether different matter if it (my actual Escort donor) had come out of the factory with bearinged top mounts.



Now, I know some here (and many others elsewhere no doubt) have done such mods and are happy with the results but none of them are me and until *I* make such changes I won't (can't) be convinced. But then maybe I am more fussy / sensitive to such things than most? <shrug> ;-(



Some of that is because I would prefer every mod or upgrade to result in a more positive experience. ;-)



Cheers, T i m

I know this is an older post, but i thought i would add in my experiences so far with the top mount problem....

first off, for anyone looking for replacement top mounts, the rangers use what the escort boys term 'small hole' top mounts, rather than the 'large hole' type. the small and large prts pertaining to the size of the hole in the top of the front suspension tower.

as far as i can find out, we cannot get the original type of mounts any more. if we had large hole, we'd be fine. but small hole? no chance.

i'm taking a bit of a chance, and fitting spherical bearing solid alloy top mounts. partly because theyre the cheapest i can find, and partly because i couldn't care less if it makes the ride harsher than the originals (after all, i will be throwing it up rocky green lanes for sport!)

I will post up some pics and a brief write up of what is involved once i have done the deed.

cheers,

Lee

In the Rally Design blurb it says that the solid mounts are only suitable for smooth race tracks so I imagine the ride quality on the road would be fairly awefull, also all the stresses would be fed directly into the tower but I would think that a Rickman would survive this unlike an Escort.
I believe the "hole" size is detremined by whether the donor vehicle was a MK1 or MK2, Rickmans asked you to specify when ordering your kit.
I'm also under the impression that roller bearing mounts raise the front a bit, might be usefull off road.
Anyway good luck with it and let us know how you get on.

Hi Tim S.
I fitted these to my Space Ranger, the reason was because I had fitted the 2.3 diesel which was a rather heavy lump, although they were expensive they did the job and the steering was better and lighter than i had experienced with the normal top rubber mounts, if you do decide to go down this route then ensure the the mounting hole and the bolt hole match you top strut holes. you can still get the old top mounts but they will be used items rather than new, try GS Escorts in Lancashire and ask for Graham.

cheers guys.

I have the MOT booked in for saturday morning. all things being well, i should be able to have a decent test on road next week.

the next proper trial will be on jan 4th - the MCC exeter trial. if they stand up to that and arent too crashy, then i believe they will stand up to anything!

I will get back to you after the trial to let you know how it goes. i might take a set of old top mounts with me just in case.......
