Fractured chasis/Steering box problems
« on: October 17, 2006, 07:10:17 PM »

Does anyone remember the link to the site that tells you if your jeep has been recalled and had the work done as i have a fractured chasis/steering box problem ???

Or is there anyone who wants a job welding somewhere near basingstoke ?

It also failed on upper steering column bearing excessively worn

Cos of these they wouldnt test the brakes for fear the steering box would come off under breaking

Apart from that its pretty solid

Found these under recalls

Recalls
1997 (January 1993-1997 model year RHD; 19,200 cars): check for stress fractures around steering box mounting.

1997: 567 cars built before Sept '96 recalled due to possibility of 'inadvertent deployment of airbags'. 1998: further recall over steering box mounting problem.

2/8/2000: 651 Cherokees recalled because airbag warning light and or airbags may deploy without warning. Airbag control unit to be replaced with modified type. Check coolant level and look under oil cap of diesel for mayonnaise indicating head problems.

August 2002: worldwide recall of 29,000 Cherokees built 1993 to 1999 to check for corrosion in front brake discs that may lead discs to separate from hubs. Official UK recall 19-08-2002. 23,146 UK cars affected. Discs to be replaced with new version if not already fitted.

29-11-2002: 7,148 Cherokees recalled because steel vacuum pipe supplying vacuum to brake booster may crack resulting in loss of brake servo assistance. Steel tube to be replaced with flexible hose.

 4-8-2003: 2,552 Cherokees may suffer vacuum leak in EGR to Electronic Vacuum Regulator tube which may cause lack of vacuum in servo and loss of servo assistance to brakes. Inspect tube from EVM to dash panel. Replace if damaged and re-route to eliminate interferance with exhaust shield.

4-8-2003: 1,848 Cherokees may lose servo assistance to brakes due to collapsed brake booster vacuum hose. Inspect vacuum hose, replace if damaged and reroute to avoid interferance with coolant recovery pipe

still searching around.

There was a recall on early RHD XJs which involved inspection of the chassis area where the steering box meets the chassis. If no cracking was present, a small preventitive welding repair was done. If cracks were found, a maJor repair, involving welding substantial reinforcement plates to the affected area was required.
Subsequently, a few of the preventitive repairs have failed and now require the major repair.

If you have a '93-'96 XJ and it has fractures around the steering box mounts, take it to any Jeep dealer and they should be able to repair it FOC so long as DCUK approve the job first.

If they won't take care of it, join and search on NAXJA.com for how to properly fix it. Once it's plated consider making or buying a c-rok steering box plate to prevent it from returning.

Took the xj to the local dealership this morning only to be told that the repair was done back in 97. I pointed out the mot sheet stated insufficient repair and they tried blaming it all on corrosion. After a few harsh words they agreed to speak to the warrenty manager when he arrived to see what could be done ( the phrase i know people usually works ). Works even better when you take the phone number for Chrysler too.

Had a phone call this afternoon asking me to take the jeep in so they could put it on a ramp to take all the appropriate photos to be emailed of to Chrysler to try and get it fixed as a faulty repair. There still saying its just corrosion but i cant see it being just that. They agreed to email me a copy of the photos they took which i should be getting soon.

So hopefully i should find out in a few days wether i can get it sorted out or have to dig deep into my pockets, £300 i have been quoted so far without them even looking at it.

i saw one of those plates while looking at lift kits. nice sustantial piece of mateal which incoperates the bumper mounting as well. I looked at mine a couple of months ago whilst replacing the radiator and saw a bit of welding. if it's a jeep fix then they should send their technicians on a welding course to teach them how to do it up and rust proof it after.

It's not just XJs that suffered either.
This is the left hand chassis rail of my YJ after a trip to Clyro in January

I will put this down to the Jeep having a hard life.

Sadly, the chassis has now split around the steering box as well, and although it now has some pretty substantial welding it won't last much longer. Basically my chassis is scrap :weep:

can you acess the front of the chassis member ?
 if so cut the end of if covered measure the internal size and consult a local steel stock holder to see if they supply a suitable size. use the box section as a internal sleeve/brace and either bolt into place or weld. Quite a common practice on german cars which are designed to collapse on an impact. not the same but the same form of principle

just thinking of a way to save you a bit of hassle

option 1

looking at the picture again, i am assuming the front of the wheel is show and the front of the vehile is on the left hand side of the picture.
 either way repairing it or scrapping the chassis its not going to be an easy job.

this idea of this repair is not a solution, i'd rather try and repair something rather than just replace, it's just the way i see things and not being part of the throw away philosophy with vehicles.

 the front cross tube will stop a piece of box section being slid into place which makes thing just a bit more interesting. It is quiet normal to slide box section into ladder chassis for strengthening or box over and seam weld, Isuzu trooper owners have to do this on quite a few parts of their cars.

the front suspension will have to be removed to enable access, and the corresponding body mounts undone and removed if possible.
 the chassis will have to be cut further down under the passenger seat where there isn't any bends. mark the chassis rail and body with referance points so it goes back in the same place. this section then can be removed.
 the front fatigued metal  then can be cleaned up and squared off.
cut a piece of box section long enough to be slid into the removed chassis rail then slid back acros the cleaned fatigue at the front when it's refitted (same for the rear) 300 or 400mm either side of the break is ideal. then weld into place after the chasis rail has been bolted back to the body. reweld the rear together with the other insert box section. drill some spot weld holes through the origional chassis and weld these to create additional strength around the chassis repairs.

grind off excess and rustproof. refit suspension etc.

option 2

slightly easier

seam weld 3/16th plate on four sides of the broken chassis rail and where the plates join.
 just the problem of straighteneing out the twist part and grinding the surfaces flat

The factory repair kit consists of two heavy gauge repair plates, one of which has 3 steel tubes attached which the steering box bolts run through. The Steering box bolt holes in the chassis are bored out to accomodate the tubes and the inner plate can then be fitted to the steering box side of the chassis rail with the bolt tubes running through the chassis. The other plate sits on the other side of the rail and the tubes project through it. The whole lot is clamped together and the plates are welded all the way round, puddle welded through multiple holes stamped through them and aroundthe 3 tubes for the bolts welded to the outer plate. When welded in position it forms a very strong repair.
To access the repair area properly, the entire nosecone of the Jeep is unbolted, radiator and condensor removed, steering box removed etc. It's a whole day's work.
