How Hot are Your Hydroboost Lines?

You've got a restriction somewhere. If it was me I would just put $30 in a seal kit pull the steering box apart and rebuild it and find the restriction than messing with a redhead or blue top box. I can rebuild that sagnaw in my sleep its so easy. 

Yes, I'm sure it's when the hydroboost started acting weird. It probably sent something downstream to the box. I'll look at rebuilding it, but it is getting up there in mileage. Might be best to get all new bearings and everything in it.

Not much in a sagnaw steering box.

 

There are only 3 bearings in a sagnaw. 1 bearing on the output shaft and 2 bearings at the base of the input and the cap. Rest is all harden parts and seals that wear out. The biggest problem is the amount of sludge that will be in the box The small orifices that are part of the power valve assembly will be where the problem will be is the valve gets gummed up with sludge.

Unknown... Just looking for a picture and it happen to come for the ride...

Do our hydroboost have a weep hole, like somewhere between mastercylinder and firewall? 

[Mopar1973Man]

Not that I know of... 

 

Mine never leaked yet.

I think because Mike always staying on top of fluids that's why his still on a lot of original stuff. Part of reason I started to try and stay ahead of game and also listened other peoples advice here and put an inline filter for power steering fluid.  And something I never considered changing before like brake fluid till parts are changed and I got to bleed the system anyways, now I'm keeping an eye on things and change when I feel needed.

[Mopar1973Man]

Inline filter will do nothing for the suldge issue your still going to have to flush the system every 30k miles. That is majority of the issue tbe fluid breaks down and suldges up just like engine oil. No filter will fix that issue.

 

Still running on monthly inspections and changing fluids when they discolor or mileage exceeded.

Mine hydro boost did not stat leaking till around 400k. Cant help but think that the exhaust brake helps with that. I have only had mine for maybe 150k but @Mopar1973Man has had his for most all of his miles. What say you Mikey?

[01cummins4ever]

Well I might be joining you all on the hydroboost rebuild, I pulled into a campground north of Denver yesterday after a 450 mile pull with the 5ver, I noticed my frame behind front wheel soaked with oil. Looks like it's PS fluid, and comming from around the hydroboost 

I guess I know what I'm doing when I get home.. 

[Mopar1973Man]

Fluid changes... Fluid changes... 

 

This why i dont buy the hype of synthetics and use cheap Super Tech fluids i can change often and keep every fresh fluid wise.

Spanner wrench.  In the pic there are bearing retainer/pre-load nuts with holes on the face.  The dowels on the wrench go in the holes to tighten or loosen the nut.

Looks like an adjustable spanner wrench
