I still have not replaced my right front Bilstein as I have not decided what to do. Too busy with work and other stuff at the moment. Strut initially leaked for a few weeks and now it has slowed down to a weep. Doing the bounce test on the front it is difficult to tell the difference between left and right. When driving the only difference I think I can feel is slightly more nose dive on the right but I could be imaging it since I know the strut is not 100%.

If the car is still handling ok then no need to nurse it, maybe drop a few psi from the tyres on rough roads.

At this stage I still believe it is the springs that are causing the Bilstein failures. Any coil that does not have the top winds ground flat puts a sideboard on the struts and this flexes the shafts.

Still delighted with my Drummond Motor Sport front struts. Now done 70,000 ms on them. Bit more cranking up needed once rear springs go in and then DooSo back to full off-road height. They work a treat with the steel bullbar and winch so nothing more needed than winding them up to proper height after adding the bar and winch. Indeed, DooSo with all the steel front and rear is very balanced and handles beautifully at the moment, so hopefully the new rear springs will not stuff up the neutral handling.

In all wrapped how DooSo rides and handles at the moment. But the test will be with full load on board.

I have nursed the Challenger in to Brisbane from Longreach and handled OK. The front right is now stopped leaking, so expect if have no oil left but the left is still leaking. The struts will be removed on Wednesday and sent to Bilstein for warranty replacement. The shocks are 13 months old but I understand Bilstein are good with there warranty even a month or 2 passed the 12 months

Of the 3 Bilstein front struts I have that have fail all have leaked oil then slowed down to a weep and when the struts have been removed have nitrogen pressure. Only s lsght loss of dampening control could be detected. All shafts were scored/dull on one side of the shaft only and in a small section where the shaft normally runs. None of the shockers have been repairable because of shaft damage and only one was replaced under warranty even though it had 30,000km of use the other 2 shockers had 40,000 and 65,000kms of use.

What coils are you using?
Are the top winds ground flat? If not then I suggest you change coils as I believe this causes the problems due to shaft flex that chops out the seals, combined with the high pressure nitrogen charge of the Bilstein design.

Best of Luck,

OJ

either change coils or shocks.

From my experience Bilstien will not warrant if the shaft is the problem as they will blame the coil and you mention dobbinson HD coils and they don't have a taper, I know, been through this whole experience.

the cost of fixing you can purchase a new billie strut for around $50 more as the rebuild and shaft costs that......

I also never noticed much change in effect of the dampening, but didn't want a catastrophic failure at the worst possible time- rather be preventative than reactive.

There is nothing wrong with the coil, just that the bilstien shocks are not suited to particular coils. you might have a chance with the supplier of the aftermarket suspension?

I'm currently running Kings Springs with my Bilstien struts. They came pre-assembled.

That is fitted to a new MQ Triton. Don't know if that's relevant.

Are the top winds of the coils ground flat?
If not I believe you will have the same problem again.

The Dobinson coils are grinded flat like the OEM were.

There was 2 importers of Bilstein suspension until 2nd half of 2016. The one in Victoria has sold the business to the one in Sydney as he was retiring. The shocks have some minor differences but almost the same. The new ones are shorter overall by 20mm roughly. The drive is great considering the wauy it was. The old shocks still have heaps of pressure besides the oil coming out.

Service and warranty is a big thing

It would be great if you could measure your front EBH and then jack a front wheel clear of the ground and measure the centre wheel hub to under guard (EBH) again. The 20mm shorter shocker on the front equates to about 40mm of suspension travel and this has got me concerned that the shocker maybe too short. What part number shocker has been used/
