Thumbs up Spring Isolators

Howdy all.

I am leaning toward installing these spring isolators (https://www.expeditionexchange.com/genuine/) in the rear spring tops and the rubber tower retainers in the front, to give a slight lift and quiet down the impact of suspension action on the chassis.

Lee relates they are factory installed on Discos and maybe other models. Anyone have experience with their net effect?

Also, what do you use to compress the spring down to do spring work?

Thanks!

Wicks-

The rear springs should just drop out when you remove the shocks and lift the frame. Even with OME springs.

With 3 or 4 inch lift springs you may need a spring compressor. Use a strut compressor Auto Zone rents them,

No need for a spring compressor for the rear of a D90. Undo the bottom of the shock and unseat it. You will be able to drop each corner enough to let the spring fall out of the top.

Those isolators work pretty good on our disco. When I installed the EE retainers I didnt put them back in and even clamped down the springs rattled a bit. Just put them back in and they are all quiet again. The do make a differance.

I just replaced mine recently, well truthfully John did I just helped him wrench a bit. Anyway, yes their great!

Well in my case we used spring compressors for the rear, I used OME 754's. These coils were stout and we couldn't have installed them without the compressors. Save yourself some money and just rent them out for free from Pep Boys, they will require a deposit.

Thanks guys.

Al, are you talking about the isolators, or springs? Did you fit the rubberized shock tower retainer to the front as well?

AWW man! Thats part of the fun of driving it. I love it when I have a passenger and I have to slam on the brakes and the rear springs pop out a little but make all kinds of noise. You should see the look on their face.

Wicks, if you put jack stands under the frame then put a jack under the axle and remove the tires, you can just lower the axle down enough for the upper part of the spring to pop out. I did this with even 3" springs with no problem.

I have ran with and without the rubber isolator and it really makes no difference at all. If you really want one though, get one at Pep Boys for $5 they have one size fits all.

Nope not the genuine ones, but rubber is rubber But, if you like, I can buy ones from Napa and put a LR sticker on there and sell them to you for an extra $10. Man I crack myself up, nothing but love

What! Come on Dave, rubber is not rubber! Strictly speaking, normal rubber is by far inferior to any and all rubber products displaying the LR logo. The price difference alone proves that!

Wicks

I don't think you'll see any drastic noise reduction with these. If you really wanted to quite down the cab you might be better off laying down some dynamat or other sound deadening material. As far as I can tell these rubber retainers were probably only manufactured for the Disco's to further enhance the noise reduction inside the vehicle. Although, if you're looking for the whole package (a silent D90) then I'd put down some deadening material & install the rubber towers as well.

i don't think a little rubber donut would be worth the time or effort on a D-90 especially to make the inside more quiet. as far as a lift you seem to have a good bit of stuff on your SW i think its effects would be be negligible at best. my .02$

Wicks,

Actually on the 110 I used the rubberized shock tower securing rings and when I converted my D2 from SLS to coils I used the rubberized spring isolators on the rear.

To be honest it's not like a night and day difference. Minimal change on the 110, but quite a change on the D2. I tried to go the CB route initially but realized that I really needed the isolators after all....much improved with them on. On the 110 it was a personal preference to go with the rubberized shock tower securing rings. She was getting a lift at the time and I was also replacing the shock towers so it was a good idea to replace the securing rings at the time and I'm glad I did it.
